Dallas Mavericks Betting Preview
The Dallas Mavericks had to endure a grueling, injury-riddled transition with a new front office led by team president Masai Ujiri and head coach Dusty May to hit the reset button on this stumbling franchise. The Mavericks were abysmal last season as they amassed just 26 wins, and you knew it was going to be tough from the start, as the Mavericks didn’t get a single game out of Kyrie Irving.
Cooper Flagg shouldered the extra workload and put together an incredible season to finish with the NBA Rookie of the Year award. The Mavericks decided to get rid of Khris Middleton, Ryan Nembhard, Marvin Bagley III, Dwight Powell, and Klay Thompson while adding Zaccharie Risacher, Santi Aldama, Marcus Sasser, and Jett Howard.
Houston Rockets Betting Preview
Meanwhile, the Houston Rockets are coming into this season with plenty of momentum after their young core stepped up and tallied 44 wins in what was supposed to be a down year. Kevin Durant averaged 26.0 points but has since been traded; Alperen Sengun averaged 20.4 points, 8.9 rebounds, and 6.2 assists per game, while Amen Thompson averaged 18.3 points, 7.8 rebounds, and 5.3 assists per game.
The Rockets were busy in the offseason as they moved Kevin Durant and Dorian Finney-Smith while acquiring Jalen Green, Dillon Brooks, Marcus Smart, and Bogdan Bogdanovic.

Rockets vs Mavericks Prediction
The Mavericks are still missing some players, with Dereck Lively II, Santi Aldama, and Caleb Martin all ruled out, while the Rockets are keeping an eye on Steven Adams, who is questionable with a calf strain. The Rockets open as clear favorites at home, but they are working so many new pieces into the rotation, and they are only 10-21 ATS in their last 31 games when favored by 8.5 points or more.
Sure, maybe the Rockets get the comfortable win in front of their home fans, but I just don’t feel that the Mavericks should be such heavy underdogs at the start of the season, especially with Kyrie Irving expected to make his return.
