Mavs don't need to accept a bad deal for DSJ. He is under contract for 2.5 more years. Then he is a RFA which means the Mavs basically control his contract for between 3.5 to 6.5 more years. I get that DSJ is upset but he is getting bad advice here with this trade demand. Cuban, Carslisle, Nelson, DSJ + Agent need to sit in a room and hash this out. Plus I really don't think anyone wants to give up a valuable asset for DSJ which is why I think he will stay.
Frustrating because DSJ development was the 2nd most important thing this year, ahead of even making the playoffs. This team will soon have $45M (Jordan/Mathews/Dirk) off the books this summer and $35M (Barnes/Powell) next summer. Every one of those guys is under performing their contract. That is $80M to play with and a 21 year old Luka on a rookie contract ready to go for the 20-21 season. That looks like an 8-10 year championship window. A 23 year old, more developed DSJ could fit in that window. I'm hoping that cooler heads prevail.
