Celtics vs 76ers Prediction: Game 4 NBA Playoffs Picks

With the NBA Playoffs heating up and Game 4 of the Celtics-76ers series tipping off on April 26, 2026, bettors and fans alike are hunting for the sharpest angle on tonight's matchup. Boston holds a 2-1 series lead, Philadelphia is missing its franchise cornerstone, and the lines have shifted in telling ways. This guide breaks down every major betting option — spread, moneyline, total, and player props — so you can make an informed decision rather than just following the crowd.

This breakdown is aimed at sports bettors, daily fantasy players, and analytical fans who want more than a gut pick. We're evaluating each betting "product" — each available wager — on its value, the underlying evidence, and the risk-reward calculus. Whether you're a conservative bettor who wants a clean side pick or an aggressive player hunting +EV props, there's a recommendation here for you.

The Situation: Why Game 4 Is One of the Most Lopsided Playoff Spots of 2026

Before diving into specific picks, the context is everything. Joel Embiid is out following an appendectomy and listed as doubtful for Game 4 — a loss that effectively removes Philadelphia's best player, defensive anchor, and the only true counter to Boston's size. The 76ers won Game 2 on the strength of a combined 59-point performance from Tyrese Maxey and rookie VJ Edgecombe (23-of-48 shooting). But in Game 3, the Celtics made an adjustment: they put Jayson Tatum on Edgecombe, and the two-headed attack collapsed to a combined 17-of-47 from the field and 5-of-20 from three.

The Celtics' bench has been an overlooked story of this series. Boston outscored Philadelphia's bench 35-14 in Game 3 alone, and leads 92-62 in bench points for the series. That depth advantage becomes even more pronounced when Embiid isn't available to anchor Philadelphia's rotation. Meanwhile, Jaylen Brown and Jayson Tatum are combining to shoot .500 from the field and .400 from three — both above their regular-season averages — at exactly the moment you want your stars peaking.

Pick #1: Celtics -7.5 (Spread)

The Core Bet

Boston is installed as a 7.5-point road favorite — an unusually large number for a playoff game, let alone a road team. But the number tells you something real. Sportsbooks aren't being generous; they're accounting for Embiid's absence in a matchup where Boston already won two games with its stars playing at a high level.

• Key feature: Celtics are 16-9 ATS as a road favorite this season and 26-16 ATS overall in road games — one of the strongest road ATS records in the league
• Edge: Philadelphia is below .500 ATS both as a home underdog and in all home games this season
• Risk: Playoff games tighten in the fourth quarter; Philadelphia's crowd can fuel a late run
• Best for: Bettors who want a clean, well-supported side with strong trend backing

Verdict: This is the anchor pick of the slate. The ATS records on both sides point in the same direction. Multiple sharp projection models have landed on the Celtics covering, and the structural case — Embiid out, bench mismatch, Tatum's defensive adjustment — supports the number. This is not a spot to fade Boston.

Pick #2: Under the Total

The Trend That Won't Quit

All three games in this series have gone under the total. That's not noise — that's a pattern rooted in how these teams are actually playing. Philadelphia's offense, already depleted without Embiid, has been further hampered by Boston's defensive rotations. The Celtics' half-court defense is forcing contested mid-range jumpers and errant threes, which keeps the pace low and the scoring suppressed.

• Key feature: Three-for-three unders in the series, driven by Boston's defensive discipline and Philadelphia's offensive limitations
• Edge: Without Embiid, Philadelphia loses its primary source of easy points in the paint and from the free-throw line
• Risk: Line setters are aware of the under trend; the total may already be adjusted lower than it would otherwise be
• Best for: Total bettors who want a trend-backed play with a clear fundamental driver

The question is always whether the market has already priced in a trend. But the fundamental argument here — Embiid's absence removing a reliable high-volume scorer — is a new factor for Game 4 specifically. NBC Sports' betting analysis identifies the under as the highest-confidence wager on the board for this game. Hard to argue.

Pick #3: Tyrese Maxey Under His Scoring Prop

Fade the Game 2 Hero

Maxey exploded for a huge Game 2 performance alongside Edgecombe, but the Celtics corrected quickly. In Game 3, after Boston adjusted its defensive assignments, Maxey's production fell sharply. The Celtics will not allow back-to-back blow-up games from Philadelphia's backcourt without a counter-adjustment, and with Embiid unavailable to draw defensive attention, Maxey will face more focused coverage.

• Key feature: Celtics made a specific defensive adjustment in Game 3 that directly suppressed Maxey's efficiency
• Edge: Without Embiid creating separation and drawing doubles, defenses can collapse harder on Maxey
• Risk: Maxey is capable of going nuclear in a must-win environment; this is a prop with real variance
• Best for: Prop bettors comfortable with individual player variance who want the defensive adjustment story

The combined 17-of-47 shooting from Maxey and Edgecombe in Game 3 wasn't a fluke — it was a design. Computer projection models have Maxey projected below his sportsbook scoring line for Game 4, reinforcing the under here.

Pick #4: Jayson Tatum Over His Points + Assists Prop

Star Playing His Best Basketball

Tatum is not just scoring well — he's doing it efficiently while taking on the defensive assignment of guarding Edgecombe, which typically indicates a player in peak form and confidence. His playoff shooting splits (.500 from the field, .400 from three) are both above his regular-season marks, which is the opposite of the typical playoff regression story.

• Key feature: Tatum is shooting above his regular-season averages in the playoffs — a strong signal of current form
• Edge: Philadelphia's interior defense without Embiid struggles to contain drives, meaning Tatum gets easier paths and draw fouls
• Risk: Tatum's assist numbers can fluctuate based on teammates' shot-making; if the Celtics blow this out early, starters rest
• Best for: Bettors who want to ride the series' best player at peak efficiency

The "blowout rest" risk is real in a scenario where Boston goes up big in the third quarter — but it's a good problem to have if you're betting an over and the lead protects itself through three quarters of accumulation.

Pick #5: Celtics Moneyline

Straight Win, No Cover Required

If you believe Boston wins but aren't confident they cover 7.5, the moneyline offers a lower-risk expression of the same directional view. At typical -300 to -320 odds for a 7.5-point road favorite, the implied probability is around 75-76%. The question is whether that's enough juice for the confidence level you have.

• Key feature: Straight win bet — removes the margin-of-victory variable
• Edge: With Embiid out, Boston's win probability in a playoff elimination-pressure game is genuinely near 75%+
• Risk: At -300+, the payout is small relative to exposure; juice eats your margin on variance
• Best for: Conservative bettors who want the win side but are uncomfortable with -7.5 in a playoff environment

The moneyline is the "safe" version of this game's directional bet, but at -300+ you're risking three dollars to win one. It works as a parlay leg more naturally than as a standalone wager unless your bankroll management favors heavy-favorite straight bets.

Pick #6: Adem Bona / Andre Drummond Under Minutes Played

The Embiid Replacements Can't Hold Up

Philadelphia's interior coverage without Embiid falls to Adem Bona and Andre Drummond, and neither has covered themselves in glory this series. Bona has picked up multiple offensive fouls in limited time, while Drummond has been a documented defensive liability against Boston's pace and spacing. If either draws early foul trouble — a real possibility given Boston's aggressive interior attack — their minutes will crater.

• Key feature: Both Embiid replacements have structural weaknesses Boston will actively exploit
• Edge: Bona's foul-drawing tendency in a playoff environment makes low-minutes outcomes plausible
• Risk: Prop availability varies by book; minutes props can be hard to find at good numbers
• Best for: Sharp prop bettors who want to bet the depth mismatch directly

Pick #7: Same-Game Parlay — Celtics -7.5 + Under + Tatum Over Points

The High-Value Combination

For bettors who want to maximize return on a high-confidence game, a same-game parlay combining the three highest-conviction plays offers meaningful upside. The correlation between Boston covering and the under hitting is actually positive — if Boston controls the pace and wins by double digits, total points are suppressed almost by definition. Tatum over is slightly correlated with the Celtics covering, though he can exceed his prop even in a closer game.

• Key feature: Positive correlation between spread cover and under — Boston blowout scenarios hit both
• Edge: SGP odds typically range from +350 to +550 depending on specific lines; the payout reflects the parlay risk while the correlation reduces theoretical variance
• Risk: Any single leg busting kills the ticket; SGP variance is real even when legs are correlated
• Best for: Bettors with smaller units looking for meaningful payout on a high-conviction slate

Comparison Summary: Game 4 Wager Trade-offs

Buying Guide: What Actually Matters When Handicapping This Game

Injury Impact — The Embiid Variable

In the regular season, Embiid's absence might cost Philadelphia 5-6 points of implied margin. In the playoffs, where defenses are more prepared and rotations are tighter, that number climbs. Philadelphia without Embiid is a different team — not just in talent, but in scheme. Their entire defensive system is built around his rim protection. Without it, Boston's drivers (Tatum, Brown, Payton Pritchard off the bench) have open lanes.

Adjustments Matter More Than Raw Stats

The Celtics' decision to put Tatum on Edgecombe in Game 3 is exactly the kind of adjustment that wins playoff series. It shows a coaching staff willing to deploy its best player for defensive purposes, not just offensive production. Philadelphia has not yet demonstrated a credible counter-adjustment — their options are limited without Embiid's gravity.

Bench Depth Is a Compounding Advantage

A 35-14 bench scoring advantage in a single game, and 92-62 for the series, isn't luck. Boston's depth is a structural asset that Philadelphia cannot match. In a potential close game late, Boston has more quality options off the bench. Philadelphia is riding its starters hard — and those starters are already shooting under 36% combined over the last game.

ATS Records Aren't Random

Boston's 16-9 record against the spread as a road favorite and 26-16 overall in road games reflects a team that wins by more than the market expects on the road — likely because their talent level and coaching create genuine blowout potential. Philadelphia's sub-.500 ATS at home as an underdog is a red flag, not a line-shopping opportunity.

Bottom Line: The Winner Is Clear

The Celtics -7.5 is the play of the game. The structural case is overwhelming: Embiid out, bench depth mismatch established over three games, Boston's stars playing above their regular-season levels, and both ATS trend lines pointing in Boston's direction. This is one of the cleaner playoff spots you'll find — a team with a 2-1 series lead, road ATS dominance, and a depleted opponent facing a must-win.

The under is the second-best bet. Three straight unders in this series isn't coincidence — it's Boston's defense systematically suffocating Philadelphia's offense, a problem that gets worse without Embiid drawing attention. If you're playing two bets tonight, Celtics -7.5 and under the total is the combination supported by the most evidence.

The SportsLine Projection Model entered the first full week of the 2026 NBA Playoffs 24-9 (73%) on top-rated NBA spread picks — and it has Boston covering here. When the model, the trends, the injury report, and the series narrative all point the same direction, that's not a coincidence. That's a bet.

FAQ: Celtics vs 76ers Game 4 Predictions

Is Joel Embiid playing in Game 4?

Embiid is listed as doubtful for Game 4 following an appendectomy. He has not played in the series and his status for any remaining games is uncertain. Philadelphia has been using Adem Bona and Andre Drummond as replacements, neither of whom has been effective.

Why are the Celtics 7.5-point road favorites?

The 7.5-point spread reflects Embiid's absence, Boston's current form (both stars shooting above regular-season averages), the established bench depth advantage, and Boston's strong road ATS record this season. For a playoff game, this is a large number — but the fundamentals support it.

Has the over or under been hitting in this series?

All three games have gone under the total. Boston's defensive discipline and Philadelphia's offensive limitations — made worse without Embiid — have kept scoring suppressed throughout. The under trend has a clear fundamental driver, not just statistical noise.

What's the best prop bet for Game 4?

Jayson Tatum's points + assists over is the highest-confidence individual prop. He's shooting above his regular-season averages, guarding Edgecombe effectively (which signals peak form), and will face a Philadelphia interior defense without Embiid's rim protection. The Maxey under scoring prop is also well-supported given Boston's Game 3 defensive adjustments.
