NBA betting trends and expert handicapping Jayson Tatum Boston Celtics

The NBA postseason is finally here, and it hasn't wasted any time making things interesting. Through the first week of play, we've already seen shocking results, blown leads, and more than a few bettors shaking their heads at their betting slips. If the regular season was a roller coaster for cashing in against the spread, on over/unders, and player props—which it absolutely was—the playoffs have already shown they're not going to be any different.

Knowing which team is going to show up and which player is going to go off on any given night has never been easy in the postseason. History tells us that every year without fail, somebody nobody saw coming steps into the spotlight and owns it. There is still plenty of basketball to be played, but with the latest insights and tips, you won’t have to guess for your future bets. Let's get into it.

Doc’s Sports offers NBA expert picks for every game on our NBA predictions page.

Back Boston ATS 

The Celtics and 76ers are at it again, and just like most years, the outcome feels inevitable. Boston is the better team, everyone knows it, and the spread isn't going to change that. Lay the points and don't lose sleep over it.

Philadelphia's season has been one long injury report dressed up as a basketball team. The weekly "is Embiid playing tonight?" guessing game wore thin fast, and Game 1 showed exactly what that uncertainty does to a team. While having Embiid on the floor genuinely makes the 76ers harder to deal with offensively, it doesn't make them a different team. It just makes them a worse version of the squad Boston spent an entire regular season preparing to dismantle.

The Celtics led the league this regular season in fewest points allowed at 107.2 per game and finished as a top-five rebounding team. They also knocked down 37% of their 3-pointers, and now they have a healthy Jayson Tatum back in the mix alongside Jaylen Brown. That is a problem for anybody, let alone a 76ers team held together with tape.

On top of that, Boston went 32-21 against the spread (ATS) against Eastern Conference opponents this season, including several covers against Philly. Philadelphia might keep a game or two closer than the spread suggests, but it won’t matter in the end. Between Boston’s depth, perimeter shooting, and elite defense, there is no reason why it can’t cover all series. Run with the Celtics.

Go Under in Magic-Pistons Series

A few months ago, most people would have given you a blank stare if you asked whether Orlando would make the playoffs. Yet the Magic just grabbed Game 1 against Detroit and turned this series into a real conversation. But "interesting" doesn't mean high-scoring.

Both teams play defense first, run limited offenses, and have no interest in putting up 120 points a night. The under needs to be on your radar for this entire series.

Before you push back, yes, Cade Cunningham is a legitimate MVP candidate. When he gets rolling, he's a problem for any defense. But look beyond him and the Pistons' offense gets thin in a hurry. This is a team that attempted just 30.9 threes per game this season, which was second-fewest in the league. That tells you everything about how Detroit wants to play. Fewer 3-pointers means fewer possessions ending in quick buckets, and that leads to lower totals.

Orlando is built differently on offense but ends up at the same destination. Paolo Banchero led the way with 23 points in Game 1, but between him, Franz Wagner, and the rest of that rotation, there isn't a consistent takeover guy. Much like Detroit, the Magic’s identity is built on stops. Game 1 was living proof of that, with the final score easily cashing the under.

You have two defensive-minded teams and one-dimensional offenses. Game 1 already told you exactly what this series is going to be. Keep riding the under.

Take Atlanta Hawks Plus Points

The Knicks and Hawks are at it again, only this time it’s without Trae Young, and Atlanta is a different team because of it. That might actually work in their favor. Before you write the Hawks off, pump the brakes, because there are several reasons Atlanta deserves to be on your radar against the spread in this series.

Start with New York. The Knicks have made an art form out of finding new and creative ways to break their fans' hearts in the playoffs, and nothing about this roster suggests that changes here. They coughed up 14 turnovers in Game 1, and the defensive issues that followed them all season didn't disappear once the calendar flipped to April. Against the right team, that's a recipe for disaster.

Atlanta is the perfect team to capitalize on that kind of sloppiness. Since Young's departure, the Hawks have built something worth watching. Jalen Johnson is running this show now, and around him is a lineup loaded with length and athleticism. With Nickeil Alexander-Walker, Zaccharie Risacher, Dyson Daniels, and CJ McCollum, this team has enough firepower to keep any uptempo opponent honest. The Knicks found that out firsthand already.

Here's the number that should get your attention: Atlanta finished fourth in the NBA in 3-point percentage this season, knocking down 37% from deep. Every time New York turns it over, the Hawks have the personnel to make them pay on the other end.

When you take into account that the Knicks had a 10-8 playoff record last year, a young, confident Hawks team with something to prove and a spread working in their favor is a dangerous combination. Take Atlanta and the points.
