One of my pet peeves is that officials change their rhythm and routine in the last minutes when a team is hurrying to beat the clock to score. They break from their normal rhythm and suddenly start running as fast as they can to set the ball. This leads to officiating mistakes, no time to look at questionable catches and more importantly, an unfair benefit in increasing scoring probability for the offense. The defense should not be penalized by a faster spotting of the ball just because their team has outplayed the other team to that point.
