There has been an abundance of awful units through the first quarter of the NFL's 2012 season, but only three units can lay claim to being the absolute worst of the worst.
We have seen plenty of pleasant surprises in the form of the Arizona Cardinals defense, the play of the rookie QB class and the Seattle Seahawks defense.
Those performances have been somewhat overshadowed by the bad play of others throughout the league.
The New Orleans Saints have fallen from the mantle of the NFL's elite to an 0-4 record.
The Cleveland Browns are proving every week that they are the worst team in football.
Squads like the Detroit Lions, New York Jets and Carolina Panthers are performing far below expectations.
So, which offensive, defensive and special teams units are the worst of the worst?
