As someone that was a GMU Scholarship athlete - the statement - "everyone who was eligible to stay wanted to return" could actually be true and yet people end up leaving. College sports are a business and a coach can show you the door without asking you to leave. They can take away your scholarship or part of it so that financially you can't personally afford to come back. They can tell you that hey I'm happy to have you stay but based on incoming players you will get even less playing time then you got this year. I lost a few teammates and 2 room mates/teammates that wanted to stay but had one of the two scenarios told to them by the head coach at the end of the season. All of them wanted to stay but choses to leave after the coaches meeting because they needed the financial help they would no longer get or were in college athletics so they could compete and were being told they would be practicing but not competing.
