One of the "Oaths" they take at the Olympics, says they will try their best at all times, be fair and honest(or something like that)!
Run up the score "MY ASS"!
You start taking things "easy" in a hockey game, and one of two things happens; You get hurt, or somebody else does! Making a move on a team mate in practise is one thing. Trying it against an opponent, do what is unatural in the game, take it easy "one time" and there you are, watching from the stands, with your knee in a cast! I know a little about this one!
You may win in other sports, but in "Hockey" you beat them!!!
