Well, I don't think he has shown that he is suitable for more offensive load but you can't be exactly sure and he is still young. There is room for improvement.Is that due to his talent level or due to the fact that Trae has to be involved with everything?
Collins has been unsettled for a while. Maybe it's because he's like you said. Or maybe it's because he wants to play in a more even system.
Still, there should have been some change after Lloyd Pierce was fired. Collins wanting a bigger role was one of the reasons for it too.
Trae and Mitchell has similar usage rates already. Moving away from Conley will only exacerbate it.
Trae spends 6.30 second per touch. Mitchell is at 5.30 but it's not hard to imagine that will go up if Mitchell moves to the PG.
