The cause of the cheating frenzy is because everyone wants to win and they have always done it by any means possible. Look back in the NFL to when the Bears and the Packers were just getting started up. The Packers got someone that the Bears wanted but that person was not of the correct age or was still in high school. At the time this was against league rules and yet everyone was doing it. Papa Bear Halas got the Packers kicked out of the league that year despite the fact this was common practice across the league including the Bears doing.

Anything to win and gain an advantage.

As for what I think of the drugs? I think that the leagues need to come down extra hard on players, coaches and owners. They need a better system than random drug testing. Today's drugs are getting better at getting around the tests and new drugs keep hitting that have no way to detect sometimes.
