Apparently one of the ways to get a waiver approval is to say your original team "ran you off" and didn't want you any more. Kirby came out and said that Cox left the team on his own and did not get kicked off the team. Supposedly, this will make it harder to get his waiver approved.
Being ran off is very different than being kicked off. Being ran off means your scholarship is gone and yes that helps a lot
Kicked off means discipline issues
