I would say Noel, Bamba, and James Wiseman sound like the type of comps that make sense based on frame and reported skill set: long, lean athletes with terrific shotblocking ability and questionable shooting skill at this stage.
All were top-4 recruits in their class (Wiseman #1, Noel #2, and Bamba #4), and all 3 averaged double-digits in PPG and RPG and 3-5 blocks per game in college, Wiseman (ruled ineligible) didn't play much.
