Any of these guys would make the Bucks a better team. Right now they have Pachulia at C, Parker at the 4/3, and Henson at the 4/5. That's really about it. I do think a defense first Center is what firs the Bucks. You can never have too many rim protectors and/or big bodied, physical presence. If he can score it's a bonus, but not necessary. If they sign Middleton, which it looks like they're going to do, scoring will need to come from Parker, Giannis, Middleton, and MCW or whoever the PG is. Plus you have the bench. So they really don't need a 16 PG+ type of Center. I like Monroe, but he's more of a 4/5 type of guy, leaving Zaza as the only guy on the roster that can match-up against certain centers across the league- and not match-up very well at that. Sure, they can play small against some teams with Monroe at the 5, Jabari at the 4, etc. but there will be plenty of times that's not enough size. All this to say this is a critical point in the Bucks history. They have ZERO big long term contracts right now, so they need to be careful before they get excited with all the cap space they have and just start signing guys that don't fit. Better off waiting if that's the case.
