Mavericks vs. Grizzlies Summer League Prediction: Boozer Buzz Meets Dallas Growing Pains

The Thomas & Mack Center in Las Vegas hosts another NBA Summer League showcase on Monday night when the Dallas Mavericks take on the Memphis Grizzlies. Remember, this isn’t a regular-season tilt — both rosters are stocked with rookies, second-year hopefuls, and two-way and Exhibit 10 players fighting for a foothold in the league, not established veterans grinding out an 82-game schedule. That context matters when reading anything into the score, but it doesn’t make the matchup any less fun to break down.

Dallas comes in having stumbled out of the gate in Vegas, dropping its first two games behind a roster built around 2026 draft picks Morez Johnson Jr. (the No. 9 overall selection out of Illinois), Sergio De Larrea (No. 25 overall, a slick-passing Spanish guard), Tobi Lawal, and Vsevolod Ishchenko. Head coach Josh Broghamer has also leaned on returners like guard Ryan Nembhard and forward John Poulakidas, both of whom saw NBA minutes with Dallas last season. Memphis, by contrast, has been the buzz of Summer League. The Grizzlies are led by No. 3 overall pick Cameron Boozer, the Duke product and reigning national Player of the Year, who has been sensational through his first few professional outings — he dropped 23 points, six rebounds, four assists, a steal, and a block in a win over Chicago on July 10, and he’s averaging north of 18 points a game across Salt Lake City and Las Vegas action so far.

Why the Market Is Leaning Grizzlies

Summer League markets are notoriously thin, and this one is no exception — you won’t find a fully priced point spread and total the way you would for a regular-season NBA game. But the directional signal is clear. Prediction market pricing and multiple sportsbook trackers have consistently shown Memphis as the favorite here, with implied moneyline probability tilting well in the Grizzlies’ favor as the week has progressed. That lines up with the eye test: Memphis has been the more talked-about, more productive roster through its first Vegas outing, while Dallas is still searching for its first win of the week. For bettors who like to shop value, that kind of lopsided public perception can sometimes create an opening on the number — but with the roster carousel that defines Summer League night to night, anyone dabbling in these markets should treat it as entertainment first and expect real volatility in playing time and rotations.

Boozer’s Big Debut and the Battle Up Front

Boozer is the headline, and deservedly so. A 6-foot-9 forward who averaged 22.5 points, 10.2 rebounds, and 4.1 assists in his lone season at Duke, he’s shown early that his feel for the game translates immediately — he was Memphis’ leading scorer against Chicago and finished second on the team in both rebounds and assists in that game. Whether the Grizzlies manage his workload closely on the second night of a back-to-back stretch in Vegas remains to be seen, since top picks are often eased into these showcases rather than played heavy minutes every night. Alongside him, 2025 first-round pick Cedric Coward gives Memphis a second table-setter capable of scoring in bunches, and 2025 first-rounder Karim Lopez adds another young, athletic wing to the rotation. It’s a genuinely deep group for a Summer League roster, which is part of why the Grizzlies have generated so much buzz out of Las Vegas.

Dallas counters with its own intriguing frontcourt pieces. Morez Johnson Jr., a bouncy big man out of Illinois taken at No. 9 overall, gives the Mavericks a rim-running threat who can also step out defensively, while Ishchenko and Lawal round out a young frontline still figuring out chemistry together. The bigger question for Dallas has been perimeter shot creation — Nembhard and De Larrea both profile as pass-first guards, and through two games the Mavericks haven’t found a consistent scoring engine to match what Memphis is getting from Boozer. Poulakidas, a sharpshooter who saw rotation minutes with the big club last year, is the player Dallas likely needs to have a big scoring night if it wants to keep pace.

Prediction and Best Bet

Memphis simply has the higher-end talent on the floor right now, headlined by a No. 3 overall pick who looks every bit the part through his first week of professional action, plus complementary scorers in Coward and Lopez who can carry the load on nights Boozer’s minutes are capped. Dallas has intriguing pieces, but this roster is still searching for its identity after consecutive losses to open the week, and shot creation on the perimeter has been an issue. Expect a competitive, up-tempo Summer League affair, but Memphis’ deeper group of proven contributors should be enough to control the second half.

• Prediction: Dallas Mavericks 78, Memphis Grizzlies 86
• Best Bet: Memphis Grizzlies on the moneyline

This is the best bet because Memphis has both the best individual player in the game in Boozer and more depth around him, while Dallas is still trying to find a consistent scoring option beyond its passing guards. In an environment as unpredictable as Summer League, betting the roster with the clearest top-end talent advantage is usually the safer path, and that points squarely at the Grizzlies.
