The Celtics have alot of potential talent but I think Brad Steven's system is so good at getting mediocre talent to play well in the rotations that they can't develops some of the better talent guys. Robert Williams, Carson Edwards, Nesmith, and Langford are all guys the Cavs would give heavy minutes to develop if they were on our team.
For the Celtics, all those guys need minutes to develop but it will cost them wins and they haven't been able to balance the two.
I think the Celtics will come to the conclusion that they have to sell of some of those young guys and get some vets back that are in the same timeline as Tatum and Brown.
