I thought we had interest in Manny Harris from Michigan. Don't know if somebody else has already got him, but I think Brian Zoubek would be worth throwing a summer league contract to since we have such a need for length and he at least has size, rebounding ability, and played four years on a winning program so he'll be coachable and a little more prepared to play some early (which is what we'd need - less need for him later in the year).
I also like Marqus Blakely from Vermont. He's only 6'6", obviously small for a power forward, but so is our current backup and unlike Davis, Blakely has extremely long arms. He's athletic and a very good rebounder.
