An antitrust trial over the NCAA's rules on how much student athletes get paid began on Tuesday.

An attorney for the NCAA examining Dr. Daniel Rascher, a professor and Director of Academic Programs for the Sport Management Program at the University of San Francisco, focused on who should be paid more between college basketball and football coaches as opposed to professional coaches.

Rascher said college coaches get paid similar salaries to professional coaches even though professional sports generate five to 10 times more revenue than college sports.

The NCAA's attorney contended college coaches have more work to do since since they have to recruit from high schools.

Rascher contends that athletes are already being paid but it is being capped.
