Necessary? Well, folks have done it the entire time. I've never seen anyone else blamed but them. Not even sure who else would be to blame.
We're talking 50+ years of them screwing over the Student-Athletes to the tune of billions. There's no one else really to blame as the primary offender in this entire charade.
Sure, ofc it's a broad brush (on an individualized level). That's inevitable when talking such a broad case and large institutions.
But the commissioners, universities (and those in power at said unis) are clearly the culprits and have been all this time. Yes, you have your Dabos and Sankeys and then your Joshs, but it's the entire power structure at blame. Less blame now than before, but there is still a MASSIVE force at play to return things to the old way and/or to continue to minimalize the efforts for SAs.
So, eff em if they aren't 100% on board. These entities had their chances to right their wrongs for decades and took it freakin SCOTUS to show them how unlawful it all was. Shameful. Their scheme is over and done. Time to take their paycuts and "let the market decide".
