If you knew half the shenanigans that went on behind the scenes, you would see this is nothing in comparison when it comes to gaining an edge.
This is true on the field, court, work place, street. If you aren't trying to win at any cost you will be taken over by those that are motivated to win by any means necessary.
Cheating aka winning by any means necessary is what makes Champions, Champions. Because even morality won't stop them from achieving their goals.
Would you rather win without "integrity" or lose with "integrity". Damn I have a hard time typing "integrity" with a straight face.
