Rose is not what he used to be but he still commands attention. He gets doubled team some times, people lose their rotations trying to guard him and this was the bad Rose version. Bulls won't have that anymore, guys will solely focus on Butler. Knicks get that type of pg who can take the pressure of Melo a little, and defenses will have to focus on 2 guys and Porzingis who I expect to take a leap this year. Knicks might make the playoffs this year depending on how Phil does with the rest of the roster. Rose, I expect him to be motivated too.
Bulls had to make that move though, but I just don't understand the point in keeping Butler. You will have no Rose, Gasol, or Noah next season. I don't see Butler by himself leading that team to playoffs. If they truly want to rebuild, they should have traded Butler as well and get some draft picks and fully rebuild. They will be stuck in that Iggy Sixers territory and Bulls fans will hate that.
