That one, or a variation, has been around forever. Tasha Pointer? or one of RU's other major players had to sit out a game for playing in an unsanctioned game during the summer.
I don't have an issue with the rule(s) since I think the college staff should have an idea what players are up to and it is their responsibility to ensure the players comply. It was my understanding at the time that it was Rutgers' "oops", and I'll put this one on Memphis.
