The Steelers had three backups in 2011, and all three of them are set to become free agents once the league year starts.
Byron Leftwich was the back up for the Steelers when they won their last Super Bowl, and is the most likely candidate to return in 2012.
Leftwich has a much slower release the Ben, and is nowhere near as mobile. He does have the ability to throw a rocket once the ball actually leaves his hands.
After leaving the Steelers after getting his Super Bowl ring, Leftwich joined the Tampa Bay Buccaneers with the hopes of resurrecting his career. He was the starter for four games before being benched for Josh Freeman.
Leftwich has seen that the grass is not greener, and knows that his days as a starter are probably numbered. If he is going to be a backup, why not be one on a team you already know, and has the chance of winning another Super Bowl?
Charlie Batch has been a great Steeler, and will continue to be as long as the Steelers will have him. Growing up a fan of the Steelers, Batch has done what most Steelers fans have only dreamed of, winning the Super Bowl.
Dennis Dixon was a fifth round selection of the Steelers, but could never pick up the system to become a back up for the Steelers, instead he spent most of his time running the scout team.
Dixon wants a chance to start somewhere, but will be lucky to find a job that will even make him the No. 2.
Though he may return to the Steelers if no other team is interested, odds of Dixon being with the Steelers in 2012 are slim.
