Randolph ... big enough to play spot minutes at center if needed, and much more skilled than Hill. Luke Jackson is a "neigh"
Ed Cota was the man. I really wish he had made it in the league. I hope you're joking. Batum is already one of the 14 signed.
Luke Jackson isn't an NBA-caliber player. Steven Hill and Shavlik Randolph might be. So it's between those two and in the small sample size of this pre-season, I'd have to lean to Randolph. He actually seems to have a little game. Hill just seems tall and well-bearded.
Hill. The 15th spot is all about a practice player. Sure, S-Bo and Hill are roughly the same size, but Hill is a traditional pivot banger while Randolph is a hustle four-but-can-play-the-five-in-a-pinch. For practice, we need a pivot to rest both Oden and Joel.
