I don't think the Rockets want to keep McGrady and trade him. If we really wanted to make a deal, we would have already made a deal. If McGrady can come back to stay healthy, his personal ability will definitely be unmatched by other members of the Rockets. If he can successfully integrate into the current tactical system of the Rockets, Houston has a great chance to enter the playoffs this season, and his return will solve many problems of the Rockets. First of all, the rocket will have a trustworthy terminator at the critical moment of the game. Neither Xiao Bu nor Ariza has a strong ability to end the game at a critical moment. Xiao Bu is limited by his height and strength, while Ariza's offensive ability with the ball is actually generalized. If there is a terminator like McGrady in the game against the Lakers, the team will not be dragged into overtime and eventually lose. In addition, the Rockets' game is very dependent on Brooks, because no outstanding perimeter player has the ball attack except Xiao Bu. Once they fall into positional warfare, only the breakthrough of Xiao Bu can break the balance of defense. If McGrady can successfully integrate into the new rocket's tactical system, McGrady's individual singles with the ball will be enough to open the gap between the opponent's defense, so the team's attack will become easier. Another point is that the rockets' inside and outside players will get better shooting opportunities because of the arrival of McGrady, especially the shooter players such as Ariza, Badinger and Battier. After the arrival of McGrady, Ariza's chances of holding the ball will be reduced, but for Ariza, who is not strong in holding the ball and attacking, McGrady's breakthrough or attracting defensive points will create better shooting opportunities for him, and the offensive opportunities may become better.
