The vast majority of college basketball players never make it to the pros—under 100 out of about 5,000 athletes—and an all-expenses paid degree provides a much better incentive than a paycheck, NCAA President Mark Emmert told CNBC on Wednesday.

"We want to make sure they get degrees, and that they really have the education that sets them up for life," Emmert said. "That's the game-changer here. Not the 3 to 4 percent who make it to the NBA."
