Most states in the country are "right to work" states. What does that mean? Well, it means you can quite anytime and you can be fired anytime. Employment law is deeply complex but one thing is generally true - you cannot be forced to work AND you are free to use your talents with other employers if you leave. Sports leagues, especially the NFL, have enjoyed antitrust exemptions that have enabled them to control their labor pool. This is balanced by the players strong union. I agree with you that mechanisms need to be put into place that limit the chaos of transfers/payments, etc among players. AND that will need to be balanced with appropriate rights for the employees (players), be it direct payments, insurance, guaranteed scholarships (currently all scholarships are year to year), etc. This is a multivariate problem that is not solved with a singular solution (NCAA has tried that for the last decade with the "you play ball and we make money" thesis which has led us to this chaos).
