"The NCAA is also aware that if it doesn’t change amateurism rules voluntarily, it may be forced to do so by law. The Fair Pay to Play Act is just one of several legislative proposals under consideration across the country. Most notably, Congressman Mark Walker (Republican-North Carolina) and Congressman Cedric Richmond (Democrat-Louisiana) recently introduced House Resolution 1804. This resolution is titled the “Student-Athlete Equity Act” (Equity Act).

The Equity Act is currently under review by the House Ways and Means Committee. If it became law, the Equity Act would alter the U.S. Tax Code to tie the NCAA’s eligibility as a non-profit to the NCAA making a major change: permitting college athletes to sign endorsement deals and other contracts for the commercial use of names, images and likenesses. Meanwhile, U.S. Senator Chris Murphy has closely examined NCAA amateurism rules and has repeatedly voiced a number of concerns—particularly with respect to the fact that college athletes are always one play away from a career-ending injury."
