So, if the Vikings had scored on a running play with less than 2 minutes to play in the fourth quarter against the Cowboys, then that would have been fine and dandy with everybody, but by scoring on a pass play in the same situation, it's considered a low-class stunt? Who the heck comes up with these silly nonsensical unwritten "rules"?
People who have a sense of respect for competition and respect for the game and respect for their competitors. You know, basically the kind of people with character, who object to the idea of deliberately trying to humiliate one's opponent rather than simply winning.
It’s pretty much the same idea that a team that is up by 10 runs in the 8th inning doesn’t steal, or pull a hit and run, etc. If you do that, you can bet that the next batter is going to get a fastball in the ear. And after that pitcher is tossed out, the relief pitcher will put a fastball in the next batter’s ear.
