The Power 5 conference commissioners are asking Congress to move forward with federal legislation regarding compensation for college athletes.

The commissioners of the Atlantic Coast, Big Ten, Big 12, Pac-12 and Southeastern conferences sent a letter dated May 23 to congressional leaders, as first reported by Stadium. The Associated Press obtained a copy of the letter Friday.

The letter was signed by John Swofford of the ACC, Bob Bowlsby of the Big 12, Kevin Warren of the Big Ten, Larry Scott of the Pac-12 and Greg Sankey of the SEC.

They encouraged federal lawmakers not to wait for the NCAA process to play out before passing a national law that would set parameters for college athletes to be compensated for use of their names, images and likenesses (NIL).

"I don't think it's indicative of anything other than our belief that the five of us bring substantial equity to college athletics and that our brands are strong,'' Bowlsby said Friday during a conference call with reporters.

Last month, the NCAA's board of governors signed off on recommendations that would make it permissible for college athletes to make money for personal endorsements, appearances and sponsorship deals that are currently against the rules. The board acted after California passed a law clearing the way for athlete compensation that takes effect in 2023; other state laws are set to take effect earlier than that.

The NCAA hopes to have legislative proposals crafted by November and ready to be voted on in January. Even with that, NCAA leaders have acknowledged the need for congressional help and a national standard that would ward off a wave of state-level NIL laws that are in the pipeline.

Some lawmakers are skeptical of the NCAA's desire to place what it calls guardrails on a compensation model.

College sports leaders have been working for months to get their message to lawmakers about what they believe are the best solutions for athlete compensation, long a thorny issue for the NCAA and its model of amateurism.

The Power 5 commissioners said the letter was to ensure lawmakers "hear directly from us, as any NIL changes will have the greatest impact upon the [Autonomy 5] conferences and our member institutions."

The letter emphasized guiding principles that echo what has come from the NCAA and other college sports leaders for months, including a ban on anything that resembles pay-for-play.

"First, those who participate in collegiate athletics are students, not employees. A critical aspect of the college model has been and remains that student-athletes are not paid for playing sports," the commissioners wrote.

The commissioners said payments should come from third parties, not universities, and boosters must be kept out of the recruiting process -- two points the NCAA recommendations also stressed.

"We intend to work with the NCAA to help shape those rules, but the congressional process should move forward in the meantime," they wrote. "In the absence of federal NIL legislation, we expect most if not all states to pass their own disparate NIL laws in early 2021, to take effect in the summer of 2021 if not sooner. So, time is of the essence."
