It also cannot be denied there have been certain patterns of teams that always get the calls and teams that always don't.
The Chiefs, Eagles, and Patriots, in particular, seem to be the darlings of the officials. Things always go their way. The Eagles false start on tush pushes and it's never called. The Chiefs' right tackle lines up offside all game, every game and it gets called maybe twice a month.
Meanwhile there are a certain group of teams continually getting screwed. That list includes the Cowboys, Bills, Lions, Saints (ever since Bounty Gate), and, admittingly, the Giants.
