The legislation would give the NCAA a limited antitrust exemption, letting it restore its five-year eligibility rule and put limits back on player transfers. It would also codify how name, image and likeness deals get regulated, the system that now lets college athletes get paid, in some cases millions of dollars a season.

Supporters call the current setup a "Wild West" era for college sports, where lawsuits have steadily worn down rules that governed eligibility, transfers and pay for decades. The NCAA is among the loudest backers of the bill, joined by a long list of major schools and conferences who want federal law to lock those rules back in place instead of leaving them open to court challenges.

For college athletes, the bill would mean firmer limits on how many times they can transfer and how long they can play, trading some of the flexibility they've gained through recent litigation for more predictable rules. The NCAA and its member schools see it differently. To them it offers legal cover they've been chasing for years as lawsuit after lawsuit chipped away at their authority.

The bill passed with support from both parties, a rare bipartisan moment that could still stall out before it ever reaches a president's desk.
