Rick Carlisle Rumors
Tim MacMahon: Mark Cuban is the general manager of the Dallas Mavericks. Let’s not get that twisted at all. Donnie Nelson does a lot of the contract negotiations, does a lot of the trade talks, but he does not make any of the decisions. Mark Cuban makes every single basketball decision. Mark Cuban makes decisions a lot of times where Donnie and Rick Carlisle have great input and sometimes makes decisions that go in the face of their advice.
