I have just never heard of a gambling violation as an eligibility issue. Its akin to a player accused of sexual assault. A school can play the kid while the charges are pending and if he is convicted, those games are not forfeited. He will assuredly be kicked off the team for the conviction, but the team did not play an ineligible player. Admittedly, I have never seen this type of scandal at Iowa that I can recall, so I could be wrong about the rule, but it seems closer to the criminal charges analogy than taking illegal benefits or being academically ineligible during playing time.
