6. Reggie Bullock
Reggie Bullock was in the deal that landed Dallas Grant Williams, but he was surprisingly released at the end of last week and ended up signing with the Houston Rockets (not official yet).
Now that Bullock has signed with another team, the Mavs can pursue him at the trade deadline if they want to. Houston likely won't be competitive this season, so they could be looking to move Bullock if the right deal presents itself.
Bullock played for the Mavs for two seasons and averaged 7.8 points, 3.6 rebounds, and 0.7 steals per game while shooting 37.0 percent from deep. These numbers don't jump off the page, but Bullock's value as a defender was invaluable.
He would oftentimes guard the opponent's best guard and provide intensity on that end of the floor. As mentioned before, Dallas is low on guard defenders, and Bullock's loss could end up hurting more than people realize.
In the 2022 NBA Playoffs, Bullock was key to Dallas' success. He averaged 10.6 points per game and shot 39.7 percent from three. He was also playing nearly 40 minutes per night, and Dalals threw him at the star guards that they faced.
Trading for Bullock would be a good move if the Mavs can buy low, and it would be an easy adjustment for him to return to Dallas.
