It's gonna be a good move to get Dirk as their general manager. There is so much love for Dirk and for sure that he'd do everything to take Luka back from the Lakers. They'll work together properly and accordingly, this is what the fans like and they should do it for most. The fanbase will get back to them.
For sure, that's going to be the scenario. Even now, Dirk is still following Luka's games (I've seen him at some of Luka's games in L.A.). So, if the Lakers end up failing this season, maybe that could lead to Luka returning to Dallas. It's just sad to see both Dallas and the Lakers struggling because of this deal. But let’s stay positive, hopefully next season, both teams can bounce back!
Same with you, I also think that if in case Dirk will take that position and Luka will have the option for his contract it's not going to be hard for Dallas to send him home, knowing how both influence to this franchise, it's just a matter of timing and right people to talk to close the deal in brining Luka back to Dallas.
There's always possibilities if timing and money will meet up and discuss the conditions, let see if how things will materialized if it's going to happen.
