For years, college sports leaders have warned that the system is spinning toward something nobody quite knows how to control.

Now Congress is considering its biggest attempt yet to put guardrails around it.

U.S. Sen. Ted Cruz’s sweeping college sports legislation entered the Senate’s final days before the August recess with something it had lacked for weeks: momentum. The bipartisan Protect College Sports Act, co-authored by Cruz, R-Texas, and U.S. Sen. Maria Cantwell, D-Washington, picked up crucial support from the Southeastern Conference and Big Ten after a round of last-minute negotiations produced significant changes to the bill.

That breakthrough has turned what looked like a stalled proposal into a potential Senate floor fight — and put Cruz in a race against the congressional calendar.

The legislation advanced out of the Senate Commerce Committee, which Cruz chairs, in June. Cruz has pushed emphatically for a floor vote before senators leave Washington for their annual late-summer break.

President Donald Trump has added his voice to that effort, urging senators to remain in Washington long enough to work through several legislative priorities, including the college sports bill.

“Without this Bill, millions of young Athletes will be hurt, programs will be canceled, Women's and Olympic Sports will go away, the fans will be robbed, and Universities will go broke,” Trump posted on social media Friday afternoon, urging senators to stop “grandstanding” and pass the legislation before leaving town.

A vote could still wait until senators return after Labor Day. But delaying the bill would send it into an increasingly crowded fall calendar, with the political complications of the approaching midterm elections looming over Congress.

And just when Cruz appeared to have cleared one of his biggest hurdles, new ones emerged.

Several senators publicly objected Friday to the accelerated timeline or filed amendments to the legislation. That could stretch debate into the weekend or leave the entire issue sitting until September.

The Big Ten and SEC changed the equation

The biggest development came away from the Senate floor.

Last week, Cruz and other lawmakers joined White House officials in negotiations with leaders from the Big Ten and SEC, the two richest and most powerful conferences in college athletics. Both conferences had withheld their support for the bill.

The talks produced enough changes to bring them aboard.

In a joint statement, Big Ten and SEC chancellors and presidents described the negotiations as “detailed and productive.”

“We listened to our colleagues, addressed their concerns, and improved an already strong bill,” Cruz said.

For Cruz, an avid Texas sports fan who made creating a national framework for college athletics a priority last year, the endorsements represent a major victory.

They also show just how much the legislation has changed to accommodate the realities of modern college sports.

At the center of the debate is money — specifically, how much schools can spend on athletes and what counts toward that total.

The NCAA's 2021 decision allowing athletes to profit from their name, image and likeness opened a market that quickly became one of the defining forces in recruiting. A later legal settlement ushered in direct revenue sharing between schools and athletes.

But another market grew alongside those changes.

So-called associated entities, including booster-funded NIL collectives, have been able to pay athletes through endorsement arrangements outside schools' official revenue-sharing limits. Those deals have already directed more than $355 million to athletes, many through booster collectives, according to a July report from the College Sports Commission.

The Big Ten and SEC wanted that workaround addressed.

Under the revised legislation, deal money covered by the provision would count toward the same $21.3 million cap schools use to compensate players directly rather than providing a separate route around the limit.

The negotiations also created another significant pool of money for athletic departments: $22.5 million that could be used for player retention, plus as much as another $5 million if schools match that spending dollar-for-dollar on women's and Olympic sports.

Put it together, and schools could have nearly $50 million in spending power under the framework.

That is an enormous number. It also illustrates what college athletics has become.

The debate is no longer about whether athletes should be compensated. The question is how the money should flow, who gets to regulate it and whether the richest programs should be allowed to keep stretching the financial gap between themselves and everyone else.

The media-rights fight

For the Big Ten and SEC, another major concern involved perhaps their greatest competitive advantage: television money.

The original legislation raised concerns about media-rights pooling, a particularly sensitive issue for conferences whose television contracts are increasingly separating the richest programs from the rest of college athletics.

Consider the Big 12.

The conference, which includes Baylor, Houston, TCU and Texas Tech, distributed roughly $39.5 million per school during the 2024-25 fiscal year. That was roughly half the amount most SEC schools received.

And the divide is expected to grow.

The SEC's new television agreement and expanded College Football Playoff revenue are projected to help widen that gap over the next decade. Texas and Oklahoma, which left the Big 12 for the SEC, now participate in that richer ecosystem.

The Big Ten and SEC did not want congressional legislation effectively forcing them to share those advantages.

Negotiators responded by clarifying that participation in media-rights pooling would be voluntary.

That concession helped remove one of the biggest obstacles standing between Cruz and the two conferences whose support could prove critical to getting the legislation through Congress.

Congress could also put the brakes on realignment

Money isn't the bill's only target.

The legislation would effectively freeze the conference map, an attempt to protect smaller conferences from another wave of realignment like the one that transformed college athletics in 2024.

Texas and Oklahoma's move to the SEC was part of a broader reshuffling that fundamentally altered the Big 12 and helped trigger a chain reaction across the country. The Pac-12 was gutted as its most valuable programs scattered to other leagues.

The revised legislation also tightens provisions involving legitimate endorsement deals and clarifies when conferences can share media-rights revenue.

Taken together, the proposals represent an extraordinary intervention by Congress into an industry that spent decades largely governing itself.

The NCAA's old model was built around amateurism. That structure has been steadily dismantled by litigation, state NIL laws, NCAA policy changes and the rapidly expanding financial power of athletes themselves.

The Protect College Sports Act is an attempt to replace some of that uncertainty with a national framework.

Whether athletes believe it is the right framework is another matter.

The opposition isn't going away

Even as Cruz picked up powerful allies inside college athletics, opposition hardened elsewhere.

A coalition that includes labor unions, athlete organizations and civil rights groups such as the NAACP urged the Senate this week to hold off until “the legislation more adequately addresses the needs and concerns of college athletes.”

The Congressional Black Caucus went further Thursday.

“The legislative process has failed to meaningfully incorporate the perspectives of Black athletes, Black coaches, Black agents, HBCUs, or the Congressional Black Caucus, despite the disproportionate impact this legislation will have on those communities,” the caucus said.

It called on Senate Democrats to block the measure until those concerns are addressed.

That matters because Cruz doesn't merely need a Republican majority.

The bill needs at least 60 votes to advance through the Senate, meaning its bipartisan label will have to translate into actual bipartisan support on the floor.

And Cruz is navigating some opposition much closer to home.

In June, the chairs of the University of Texas and Texas A&M University System regent boards sent a joint letter to Cruz and fellow Texas Sen. John Cornyn opposing the legislation as it was then written.

Those aren't insignificant programs in this debate.

Texas and Texas A&M possess two of the richest athletic departments and most powerful donor networks in college sports. Cruz himself has described them as the two Texas programs “certain to survive” without systemic changes.

The revised legislation now has the SEC's support, and Texas football coach Steve Sarkisian has acknowledged the potential benefit of a salary cap. But Cruz still risks finding himself at odds with two enormously influential athletic brands in his home state, where players collectively command tens of millions of dollars in NIL value.

Elsewhere in Texas, the reaction has been much different.

Texas Tech regent and former Red Raiders lineman Cody Campbell, founder of the nonprofit Saving College Sports and a key White House adviser on the issue, celebrated the Big Ten and SEC's reversal as a “better future for college athletes in all sports.”

That divide gets at the heart of the entire fight.

The biggest brands are well positioned to thrive in a largely unrestricted marketplace. Smaller athletic departments have far more reason to fear what happens if spending continues escalating.

College sports' next era could be written in Washington

The Protect College Sports Act is not simply an NIL bill anymore.

It is an attempt to answer questions college athletics has spent the past five years struggling to resolve on its own: How much can schools pay players? What role should booster collectives have? Can spending be capped? How should conferences handle television revenue? Can another round of realignment be stopped? And how much enforcement authority should the NCAA retain?

The answers could determine whether college sports develops something resembling competitive balance or continues down a path in which financial power becomes increasingly concentrated among a relatively small collection of programs.

Cruz now has something he didn't have just weeks ago: the backing of the Big Ten and SEC.

He also has support from a president openly pushing the Senate to act.

But congressional momentum can disappear quickly, particularly when the clock is running toward a recess and senators begin demanding changes.

Even if the bill clears the Senate, the fight won't be over. It would still have to pass the House, and the two chambers would have to resolve any differences before sending a final version to Trump's desk.

For an industry that has undergone almost continuous upheaval since NIL arrived in 2021, that makes the next few days potentially consequential.

College sports spent decades fighting to preserve the old system.

Then that system cracked.

Now the question is whether Congress will be the one to build its replacement.
