Controversy is defined as a prolonged public dispute, debate, or contention; disputation concerning a matter ot opinion.
For most fans, they can find a few controversial calls in every game they attend or watch. Don't believe me? Think about all of the times that you hear fans complaining about the referee's costing their team the game because of a bad call or a missed call.
Many times these calls end up having no effect on the outcome of the game, but once in a while there is a controversial call that will end up changing the outcome of the game. Remember Jerome Bettis's heads-tails call to begin overtime in the 1998 Steelers at Lions Thanksgiving game.
With replacement refs starting the regular season, 2012 had no shortage of controversial calls and plays. Keep in mind that not all controversial calls involve the men in stripes. It could be that a coach decides to stick with a certain player, or a coach gets let go at an odd time in the season.
Read on to find out what the 10 most controversial calls of the 2012 NFL season were.
