Andy Dalton is the Bengals quarterback and he will start, as long as he's healthy, in every game of the season. Every good team has a capable backup, though. If the worst case scenario were to take place and Dalton were to be injured, the Bengals would need a quarterback capable of leading the offense.
On the roster:
Johnson was signed on March 21 by the Bengals. He had previously spent four years in Tampa Bay with the Buccaneers and one season with the Browns. He has completed 96 of 177 passes for 1,042 yards, five touchdowns and 10 interceptions for a 57.7 passer rating. He isn't the best pure passer, but he's familiar with Jay Gruden's system and he's athletic enough to possibly do some damage with his legs.
Skelton was claimed off waivers on April 30. He was a fifth-round pick out of Fordham in 2010 by the Arizona Cardinals and has played and started 17 games over the last three years. Overall he has 320 of 602 passes for 3,707 yards, 15 touchdowns and 25 interceptions for a passer rating of 63.0. The Cardinals have bounced back and forth from quarterback to quarterback since Kurt Warner's retirement. Skelton had some quality moments, but he struggled as well. He may need only a new setting to be successful in the league.
Robinson was signed by the Bengals in September of 2011. He was a seventh-round pick out of Oklahoma State by the New England Patriots in 2010. After he bounced from the Patriots to the Seahawks and Lions and finally to the Bengals, he was placed on the team's practice squad where he has spent the 2011 and 2012 seasons.
Not on the roster:
Taylor Housewright and Ryan Radcliff both attended rookie minicamp as undrafted free agents to try out for the team. Neither currently have contracts with the Bengals.
While the Bengals are going to start Dalton, the team's backup quarterback has yet to be chosen. The first scheduled Organized Team Activities (OTA's) are set to begin on May 20.
Who do you think the backup quarterback will be?
