Follow up on Oliver v. NCAA

If the NCAA has to change their amateur eligibility rules in light of the Oliver ruling, here is an idea as to how they might do it:

My personal suggestion would be to change the definition of what it means to be an amateur so that student athletes lives aren’t ruined so easily by a mistake. A player shouldn't become professional the second he/she signs a professional contract, but the second he/she plays as a professional or receives money under the contract. (The NCAA can create a window such as before college and during the summer when the player may sign and/or negotiate a professional contract. If it is still in place when the college sport starts, then they lose their eligibility.)

I welcome your thoughts.
