You mean like when the refs screwed the Steelers bettors vs Chargers in 2008, or when the refs screwed Seattle in the super bowl vs Pitt?
It actually happens every single week where the refs screw a team over, its all part if the game. If you're gonna throw your arms up about the Dallas/Lions game, you better do it almost every week........
missing holding calls happens every game. throwing flags that are marked off then put away inexplicably does not happen in every game. or, well, ever...before last week
