A RevShare cap has been already legally imposed with the House Settlement. And legal NIL is uncapped.
Also, Cruz-Cantwell includes language that leaves open the possibility of athletes eventually unionizing with a CBA. And of course, most every other pro league with athlete CBAs have athlete salary caps and no caps on coaching salaries so Chris Murphy should perhaps rail on those leagues as well.
And if Chris Murphy is going spout out about this bill, then offer an alternative solution in doing so which he doesn't. And his claim that "all of the money" beyond RevShare goes to college administrators is nonsense given that a significant % goes directly to support non-rev sports.
No it hasn't, which his why any attempts to limit player payments have been struck down in any court case that has been brought to any district in the country. Just because the NCAA came to an agreement with an attorney and it was approved by a judge does not make it a binding agreement to people outside of that lawsuit.
You cannot unilaterally impose a revshare cap without the current players getting a say in how large that cap is.
As for your second paragraph, have you not noticed that NFL head coaches cannot leave for another job while under contract without their current team's permission?
