no thesis needed... simple greed...
Why else would 91 make a returning player pay a tryout fee??

If clubs such as 91 had a conscience (clearly not), they would at least apply the tryout fee to the tuition...

I hate to say it, because I know and like most of the club owners, but it is nothing more than a shake down to returning players...

what would they do if your son was a good returning player but did not try out?? just let him walk over the $50 or buckle, because they want to protect their brand?
