re: What is it realistically going to take to overthrow the NCAA?

I wish the Federal Govt would cut funding to State Universities unless they join the NCAA. (The only way to give the NCAA any real power.) Then the armature model is enforced by all funds to athletic departments being paid directly to the NCAA. The NCAA keeps 5-10% for administration, then sends a prorated portion (25-30%) to each conference to split amongst the member schools. Schools can also apply to a committee for extra funds to update facilities as necessary.

The remaining 60-65% goes back to the academic side of the universities...you know, to spend on the education that all the people talk about.

Coaches contracts go back to reasonable amounts. Most Title IX issues go away. Facilities are nice, but the arms race of stadiums and facilities no longer takes place. People stop talking about paying athletes, tax payers and students get a break on funding tuition for school. Everybody except the coaches and conferences win.
