My hot take is that the Bucks should trade Lopez while his value is still high, he’s good but old and limits their defensive options since he has to drop.
The Bucks need an identity change, Lillard can’t fight screens like Holiday does and that means Lopez has to come out and their defense falls apart.
One of the old sayings is that America is better at developing guards and Europe is better at developing bigs.
AAU is heavily focused on flashy guard skills and a lot of big mens development suffer ala James Wiseman. Euro leagues develop more fundamentals so you get more traditional big men skills there.
