Spelling mistakes aside, I agree that Rondo has a very high ceiling. I loved watching him at UK, and was very hopeful h would fall to the Cavs in the draft (although that wasn't a very realistic hope at the time).
As for Hickson, the guy has made rapid improvements this year, mostly due to working and training with Lebron. He has a very high ceiling. He has the natural athleticism to be great. He just needs the right guidance
