We should take a good look at Robert Upshaw, he's had a few problems with marijuana in college, but sometimes kids do mature out of this crap.
If he could ever be convinced in the error of his ways, he is a good late round choice. 7 feet, very long and strong, he loves protecting the rim and being the man in the middle.
WCS is very up and down, it's obvious that Townes is the more offensive talented of the two, but WCS has a great motor, but doesn't seem to rebound for his size.
I'm thinking the two playing along side of each other is causing the stats of both to suffer a bit.
I like Butler, and honestly never thought of him as a SF, more of a SG, but he does have the size to be a SF.
