Big time college athletes are nothing more than professionals. Big time college sports hasn't been amateur for many years now and the money is finally going to be its ultimate undoing (wow, a Batman reference!). It will destroy college athletics? The amateur model was destroyed a long time ago.
This situation reminds me of the way tennis and then track and field used to be when "amateur" athletes made a ton of money under the table. Everyone looked the other way and the situation just got worse until it finally exploded.
It is not hard to see how this might develop into a reasonable model. Any union would be constrained by Title IX limitations. It would create a different paradigm, which is sorely needed.
Of course there would have to be a CBA, probably with the P5. The other conferences would probably not be involved since the money just isn't there. There are many issues and all ot ehm cost money. So what, coaches are getting $20-$30 mullion contracts and I would rather see some of that money going to the players. A union would probably demand a fair share of the proceeds in benefits and to get it they would have to agree to a great many things including eligibility, transfer rights etc.
Representation will not be an issue as some of these smart athletes majoring in sports law and related majors will make a career out of being the union officials and each year classes of player reps will be elected. No biggie - this isn't rocket science.
The only way these kids are going to get a fair shake is with a union. I don't like unions but I realize that they are the only thing that levels the playing field and are many times a necessary evil.
