Cheating has been at the forefront of sport in recent years, what with all the doping and steroid use. Soccer Lens has an article showing that this isn't a new phenomenon. Athletes have been cutting corners and doing everything they could to get an edge for many years. Take this truly despicable human being, boxing trainer Panama Lewis:

The lowlight of Lewis’ career was the 1983 fight between Lewis Resto and Billy Collins Jr. in which Lewis removed most of the padding from Resto’s boxing gloves. He also soaked the tape that went on Resto’s hands in plaster of Paris, meaning Resto was basically beating Collins Jr. with a plaster cast for ten rounds. Collins Jr.’s vision was blurred after the fight, leading to depression and a death nine months later in a car accident that some believed to be a suicide.
