If you qualify the question to be the greatest college player I saw live, I will agree on Magic Johnson. But, I never hear anyone mention that for most of MSU's championship season, Greg Kelser was usually the best player on MSU's team. Kelser was a really undersized PF/Center (maybe 6-7/6-8, thin, but strong), who was tough as nails on both ends of the court, could run like a deer, and could jump higher than anyone he played against.
