Sports wagering experts say it was a matter of time before college gambling scandals surfaced. Last week, the Alabama baseball coach was fired after suspicious wagering activity was detected on a game involving the Crimson Tide. This week, both Iowa and Iowa State announced gambling investigations involving some of their athletes. Keith Whyte is executive director of the National Council on Problem Gambling. He expects investigations at other schools to follow. East Carolina assistant professor Michelle L. Malkin says sports betting has become part of college culture. NCAA rules prohibit athletes, coaches and staff from betting on most sports.
