It has always come off as a little strange that college football gets unpaid players to sign legally-binding contracts while coaches are free to roam to wherever they wish.
This past June the NCAA took a step in the right direction when it comes to transfers by lifting the former “permission to contact” rule, which essentially allowed coaches to block players from leaving for certain schools.
One could only imagine the legal fight that would ensue if a coach was presented with a similar restriction. Say Nick Saban wanted to leave Alabama, but was told he couldn’t coach at any other SEC school or any team that had Alabama on its future schedule (a common restriction for players).
