"Naive" is the best thing I can say about this.
Make Freshmen ineligible again - I am afraid the ship has sailed on this. To do this, the NCAA would have to negotiated contracts with the leagues and the player's unions. Good luck with that. Plus, there is a huge difference in baseball, basketball, football, volleyball, lacrosse, etc. Two examples: Baseball has their own feeder group in the minor leagues, Basketball has gone international. I am sure some players at Kentucky basketball are happy to put their year in, make it two and they will be playing for Moscow until they are NBA eligible. I can see doing this for football, seeing that it is played so early in the kid's transition to college. But I fear it will really just end up with tons of kids coming into school early and missing their senior years of HS. Make 'ships good for five years - When negotiating contracts, I always think "make all issues be equally binding". This is a no brainer. Also, let the kid out of the five year 'ship if his head coach changes, with no penalties. Allow players endorsement capabilities - this is a non-starter. There is no difference here then just paying the kid. Schools will set up companies that will pay kids for their endorsements just to come to the school. They will be professionals, lock, stock and barrel. Just give them "gold pants". If you do this, you might as well just pay them. There is no real difference. Deny Athletic Department Autonomy at Universities - not sure what this is supposed to solve. I mean, look at NC & Syracuse. Do you really think other departments wouldn't comply to keep their $50m/year revenue stream? Give players academic credits - I like this idea. In fact, I brought it up on this very board over five years ago. The risk is that you water down the impact of the first 4/5 years when a player is eligible. However, we are kidding ourselves if we think kids are getting a good education while playing, say, football in the SEC. However, I can see making a kid declare a major, take 15+ hours each semester, maintaining a minimum GPA, and still giving him/her credits toward another three years after eligibility is used up.
