The Bucks starters have been exceptional, but their bench has been horrible. Bobby Portis is a part of that. He has the 3rd worst +/- in the league for a player and he is super inconsistent. He his terrible on defense and very inconsistent on offense. In this trade, the Bucks would get back Finney-Smith and Wendell Moore. This also halves the Bucks play more small ball to start Giannis at center. They get a reliable PF that can work the perimeter and interior next to Giannis.
The Bucks rotation now: Pg: Dame/Rollins Sg: Andre Jackson Jr./Gary Trent Sf: Khris Middleton/Aj Green Pf: Finney-Smith/Prince C: Giannis/Brook
