I'm confused as to why the baseball rule, the NFL rule, or no rule would effect most CBB teams in more of a negative manner than the current rule. With one notable exception, the one and dones have had a pretty small impact on who wins a championship. There are over 1100 players in just the top 7 conferences alone, the name of the game is still evaluation and development, you have to stretch your mind pretty far to conclude that this would change because 3 or 4 kids a year never step foot on a campus and another 3 or 4 kids stay 3 years instead of 2.
