The raptors could use a Center and achiuwa hasn't been as good as they were expecting him to be, so getting christian would would be great. The Mavs get Fragic along side luka so that he stays happy and they also get rid of Dwight Powell's big salary The rockets get a young pf/center in achiuwa to partner along side KPJ,Jalen Green,Tate and Apleren SUngun (that's a great starting 5 for their future)and a decent veteran in Dwight powell for all their young players.
