KZ Okpala was released by OKC. Maybe he could be a candidate for a two-way contract? Not a consistent shooter (yet?) and supposedly not a great defender, but he has good size (6-8), great athleticism and is still only 22. I don't understand why OKC released him, though.
There also has been some twitter chatter that Taurean Prince might be a buyout candidate and he would be perfect as he shoots almost 40% from 3. But Minnesota is very much in contention for the playoffs, so I don't think they will be the ones to cut a useful player. He would be a great get, though.
