Larry Bird.
Bird led his team to an undefeated regular season and the national championship game. His only real offensive help came from Carl Nicks, who did nothing at the next level. Bird made Nicks, and everyone else on the team, better.
In comparison, Maravich:
Pete never took his team further than the NIT (as a senior). His main help came from three players who went onto brief careers in the ABA (Danny Hester, Bill Newton, Al Saunders). For the most part, the other players weren't incorporated into the offense (except in the NIT, when Pete fizzled and Hester was the team's tourney scoring leader). Pistol had free reign to do everything himself.
Both were entertaining but I'll take Bird. He not only put up numbers but led his school to its only national success.
Maravich was entertaining but didn't win much. He shot the ball more than 40 times a game because his dad was the coach.
Other contenders: Bob Lanier at St. Bonaventure. Had he not gotten hurt in the semifinal, the Bonnies might have won it all.
Bill Bradley at Princeton. He was entirely the reason the team went to the Final Four.
