Agreed. Butler on the other hand I go for.
A more realistic option would be Khris Middleton.
His under contract for the next 3 years, at around $14M a year. Has been known as a good defender, is a 40% 3pt shooter, and is only 25. Gets 5 ast per 36 as well.
So why would Milwaukee trade him? Well, Malcolm Brogdon has had a stellar rookie year, and is a lot cheaper than Middleton. The Bucks might want to create room to start Brogdon at SG.
Creating capspace and getting picks would be a good idea for Milwaukee. They need a PG, and are near the cap line. Henson is also expendable with Maker showing promise, so we could take him on as an ideal backup C as well.
So heres an idea:
BKN Gets: Crabbe, Leonard
MIL Gets: Vonleh, Lin or late BKN pick, MEM 1st, CLE 1st,
POR Gets: Middleton, Henson
Milwaukee gets their starting PG in Lin, or they clear nearly $25M in salary.
BKN Gets 2 young players at good value.
We get our starting SF, and backup C, while keeping our top pick.
