Biased Refs in NFL

If you watched last Sundays NFL playoff game of the Lions vs. The Cowboys you know that there are biased refs in the NFL. There were many examples of this throughout Sundays game. Many holding calls were not made throughout the whole game and most noticeably on Dallas's last play in the redzone, allowing Tony Romo an absurd amount of time in the pocket to find an open receiver.   

This was probably the most recognized biased call of the game. Initially the refs called pass interference but after "further review" of the play the refs picked up the flag and it was fourth down. That oblivious call ended the game for the Lions and the next drive Dallas scored, and made the final score 24-20.
