Bring Allen back to Milwaukee. Move on from Pat for Simone who flashed a bit last year only to be sidelined for most of this season, could be a major pickup for the Bucks playoffs run.
The Suns don’t need Allen as much as they need a bully/enforcer at the four position who can also spread the floor. Allen is a talented player but they have enough talented guard/wing players so Portis would be more valuable.
The Pistons trade a guy who’s playing 15 minutes for a guy who’s playing 15 minutes, the difference is (they get a second) but also they get a guy who has playoff experience (and success) in exchange for a guy who could be good someday, but they aren’t going to give the time to develop because they have a ton of young talent that they value more.
