I don't think so. I think adding those guys and retaining a couple cheap rotation quality front court guys, like McGee, Kamansky and/or Biz... I think that team would, once again, be in the running for a very high seed in the west. They would also have the ammo, through draft picks and players, to swing for a major star if one became available.
Something went wrong in that locker room during the Mavs series, I've been an Ayton backer but... him not capitalizing on the trash the Mavs were throwing at him on defense was inexcusable, our guards are getting double teamed, every freaking play, and Ayton isn't sealing out guys, he isn't making himself available deep... basically all he did was set weak screens. If we could get a return that huge for him, that keeps us in contention now and makes us a stronger contender in the future, that would be impossible to pass up on.
Ayton, at the peak we've seen him play, is a better player than anything we can get in return, we just don't see that guy enough.
