I want Ayton so I would keep Conley plus some bigs for that trade in February. Since the team is selling they may appreciate less long-term salary.
I really don't see Ainge trading for a center that makes $35 million a year. As the front office starts to build the roster back up over the next few years, I think center will be the position they view as the least important, and they spend the least amount of money on.
