Just an example of trying to get an advantage. I loved Shula doing it, but Jets fans at the time were furious.None of this was cheating because it was not illegal..if u watch European soccer, teams water the field to make the ball roll slicker. Other teams keep it dry to make the game scrappy. Nothing wrong with it.
Cheating for me, is using illegal methods to figure out the opposing team's plays before they are called. What Michigan did was cheating if Indiana has a system to do that, its also cheating. Not saying they are.
