Backups in the NFL get very little playing time with the 1st team offense. When a starter goes down to injury the game plan for the backup is to play conservative, no turnovers and try and win games.
When Andy Dalton went down with a injury McCarron came in and did exactly what he was supposed to do. McCarron won games and got the Bengals into the playoffs. With McCarron at QB the Bengals should've beaten the Steelers in a playoff game, he is more than ready to be a quality QB in the NFL.
In the end I am very excited about our QB situation. We have a QB in McCarron that can take a talented offense to the playoffs and he will help the young QB's on the roster. I don't think I have ever been more excited about our QB situation.
