🔍 76ers vs. Celtics Game 1: Preview

This is one of the great rivalries in all of basketball and it is back for the 24th time in playoff history 🔥. The Celtics earned the No. 2 seed with a 56-26 record, while the Sixers secured the No. 7 seed with a 45-37 record after their play-in win over the Orlando Magic on Wednesday night.

The big storyline heading into Sunday is health. The Sixers may be without former MVP Joel Embiid for part or all of the series due to his recent appendectomy. That is a massive blow for Philadelphia on paper, but Maxey showed against Orlando that this team can compete without their superstar. He dropped 31 points in that win and looked every bit like a player ready for a big postseason moment.

On the Boston side, the news is much better. Jayson Tatum is healthy and looking recovered from his Achilles injury, playing a secondary role to all-NBA star Jaylen Brown on a team that rebuilt itself on the fly and enters the playoffs as a genuine championship threat.

Do not sleep on the 76ers in this series though. Philadelphia owned the best clutch-time defense in the NBA this season, holding opponents to a defensive rating of 98.6 in 174 minutes of clutch play, and both of their regular-season wins against the Celtics were decided by one or two points in the final minutes. If Maxey can keep doing what he does and the Sixers can keep games close into the fourth quarter, this is a much more interesting series than the odds suggest.

🎯 Our Pick: Maxey 30+ Points

This is the bet we are building the whole piece around and for good reason 📈. Tyrese Maxey just dropped 31 points against Orlando in a high-pressure play-in elimination game without Joel Embiid on the floor. He did not just survive without his superstar, he thrived. That kind of performance does not happen by accident.

Boston's Celtics are heavy favorites here and entered the series as 10.5-point favorites in Game 1, which means the Sixers are going to need Maxey to be the engine of everything they do offensively from tip to buzzer. More usage, more shots, more opportunities to get to the line. That is a recipe for a big scoring night, and at Over 28.5 points on BetMGM you are getting a very reasonable number for a player who just showed he can hit 30 in a pressure game 🔥.

This is the prop we want PA bettors to grab first with that $10 opening bet using code BOOKIESBG150 at BetMGM Pennsylvania. Win that bet, collect your $150 in bonus bets and you have plenty of ammunition left for the rest of the series. Check out the full expert breakdown at our NBA picks page 🧠.

💰 The Real Long Game: 76ers Series Futures

Here is where it gets really interesting for Pennsylvania bettors who believe in this team 👀.

Yes, Boston is the better team on paper. The Celtics won 11 more games than the 76ers during the regular season and hold a 15-7 historical edge in their playoff series head to head. The books know all of that and have priced the series accordingly with Philadelphia as heavy underdogs.

But consider what the 76ers actually bring to this matchup. Philadelphia owned the best clutch-time defense in the entire NBA this season, holding opponents to a defensive rating of 98.6 in clutch situations, and both of their regular-season wins against the Celtics came down to one or two points. Tight finishes are what this rivalry produces. Add in that Tatum is still shaking off rust from his Achilles return and that Maxey is playing the best basketball of his career, and a 76ers series win is not the fantasy it looks like at first glance.

The books have Boston at -900 to advance in the series, which puts Philadelphia's series price at something in the range of +550 to +650 depending on where you shop. That is real money if Maxey and the Sixers can pull off what would be one of the bigger upsets of the first round.

Even if you are not fully sold on a Philly series win, think about this as a value play. You are getting close to 6-to-1 on a team with elite clutch defense, a top-five scorer in Maxey, and an opponent whose best player is still finding his rhythm. That is the kind of price that makes sense to sprinkle on as part of a broader series betting strategy 💡.

Use your $150 in BetMGM bonus bets earned from the Maxey prop to take a shot on the 76ers series futures. Check the latest series prices at our playoff odds page before placing.
