I'd move Jaylen for Butler anytime - regardless of Kyrie's feelings. Butler is a better player.
As of this moment, yes. But you have to look at the totality of the situation...age, contract, injury history, talent projection, etc. Butler will be 29 by the start of this season, but he has the knees and milage more of a 33-34 year old. Tom Thibodeau, like many players that he's coached, runs his guys into the ground. He's never exactly been known as a coach who understands minutes, bench usage, and proper rotations. So while he may be turning 29, in a basketball sense, he's much older than that.
Now just look at his talent...he's peaked as a player in my opinion. At 7+ years in the league, he is who he is. And if you break down and rate his game, is he the better overall scorer? Right now, absolutely. But outside of that, I put JB right up there in every other facet of the game with Jimmy Butler. So when you look at it that way and then add in that Brown will only be 22 at the start of the season going into his 3rd year?
No thanks, I'll keep JB and if that means Kyrie leaves, then you have Rozier has insurance. And you play and build around more of the wings than you do the point guard.
