The system for safeguarding athletes in U.S. Olympic sports might be on the cusp of a major revamp, with an independent commission set to propose sweeping changes and lawmakers saying they are standing by to act.

The congressionally appointed commission has finished its two-year study of how the system has worked and is set to publish its findings this spring. The commission’s two co-chairs told ESPN that they will make recommendations on at least three major issues: the scope of the U.S. Olympic system’s governing body, which spans from elite Olympic athletics to youth sports; athlete representation in decision-making positions throughout sports institutions; and the frequent concerns they heard about the U.S. Center for SafeSport.

The commission’s co-chairs, Dionne Koller and Han Xiao, called their work a “once-in-a-lifetime” chance to “reconceptualize” how amateur sports are organized.

“It will be up to Congress to take the next steps, which we hope will include new legislation based on our recommendations,” they said in written answers to questions from ESPN.
