LeBron James Rips New NCAA Agent Rule ... 'They BIG MAD'

LeBron James is taking shots at the NCAA's new agent certification criteria ... claiming the organization is directly attacking his partner, Rich Paul, but "nothing will stop this movement."

The NCAA sent out a memo to NBPA certified agents on Monday ... saying any players looking to test the NBA Draft waters must be repped by an NCAA approved agent -- if they want to keep the door open to return to college.

The criteria to become an approved agent ... a bachelor's degree, certification from the players' association for at least 3 years, and pass an in-person exam at NCAA headquarters.

These guidelines will preclude Paul -- who reps Bron, Anthony Davis, Ben Simmons and other huge names -- from repping this group of college players ... 'cause he doesn't have a bachelors degree.

In a memo sent by the NCAA to agents, obtained by the Athletic, the NCAA's reasoning behind the rules is to "protect collegiate eligibility of their athlete clients."

LeBron -- who dubbed the new criteria the "Rich Paul Rule" -- doesn't see it that way ... tweeting "Can’t Stop, Won’t Stop! They BIG MAD and Scared. Nothing will stop this movement and culture over here. Sorry! Not sorry.."

As for Paul's roster of superstar clients ... the new rule will have no effect on their representation.

But, if Rich wants to rep college stars considering a jump to the league while still maintaining college eligibility ... enroll in school and hit the books???
