AB is pretty much what he is, a 3+D guy for a contender. Marcus has better playmaking ability, but is not much of a threat from outside.
I think Smart is more likely to stay just from what they are both going to get for their next contract.
I think rozier can do everything Bradley does, plus has a handle and play making ability. Maybe not all NBA defense, but he appears to be a solid defender.
So who has the highest ceiling of those 3?
