I'd draft Gray somewhere in the 20's. I think he might be a solid 8 and 7 guy in the NBA.
I really like Tucker as a college player, and I might take him in the first round as well. I think Tucker will be able to score some in the NBA, and might be good enough all around to actually make an impact, but at 6-6, I'm not taking him much higher than mid-20's. If he is 6-8 or 6-9, I take him 10 picks higher, but he isn't.
Butch might get a shot as well. I've never liked him, but I would have him on my board in the 2nd round, and would bring him in as an undrafted FA for sure.
