Yeah well they have an embarrassing wealth of frontcourt depth between Dalembert, Henson, Sanders, Ilyasova, Udoh, and Gooden. Not that any one of them is a world beater, but they are all serviceable and it would make sense to move one or two of them for a SG upgrade if they can. Monta is just a horrible fit since he replicates Jennings, and they are in a decent position to upgrade.
Or if we want to dream big, they could maybe try to package Ilyasova+ for Pau if Ersan can get his act together. He'd fill the stretch 4 role for the Lakers perfectly (if he stops sucking) and I think Pau would instantly make the Bucks a top 5 team in the East.
