Beef, you can call a wide variety of subjective calls throughout a football game. it can be argued holding or offensive pass interference could be called on 50 percent of passing plays. So yes that was a penalty. but it was a penalty that did not allow for any further plays. To lose a game on a subjective call is basically a ref deciding a game, and the other side of the coin was to allow two equally competitive teams play out the rest of this game in overtime. Which would allow for the players to have more say in who wins the game and hence give more satisfaction to consumers.
As a viewer of sports all you want is for the players to decide the game. I am ok with the blackhawks winning the stanley cup. They were better than the flyers. If i was a bengals fan I would not be ok with losing to the chiefs last night.
