Someone on Reddit made an interesting post that the GM of Dallas most likely is falling on the sword to cover for the Mavericks new owner.
Not to mention the reputation the new owner has overall, it would seem she wouldn’t have too much of an issue to let the GM take all the blame for her ultimately not wanting to pay their best player.
Don’t get it twisted, he is an idiot for not trying to get a better return on trading currently one of the best players in the league.
My thing is, he might have not wanted to trade Luka also, but was given a directive from the person who signs everyone’s checks.
