But who are the low-key free-agent quarterbacks who also may get interest? At least three teams in the AFC North need proven backups who can potentially push for a starting job.
Here are some names to keep an eye on:
Skinny: Bulger is the ideal backup. He has a wealth of starting experience and could still win games as an injury fill-in if needed. The Ravens want him back but price could be an issue.
Skinny: Backing up both Mannings is a thankless job, but Sorgi has done well in limited action. He's thrown for six touchdowns and just one interception and has a 65.5 completion percentage in seven years behind Peyton Manning in Indianapolis. And most recently Sorgi was hurt and didn't see the field behind Eli Manning in New York. Sorgi could be of interest to the Cincinnati Bengals.
Skinny: Thigpen hasn’t played much since the 2008 season but had a productive year (2,608 yards, 18 touchdowns) when given the opportunity. After toiling in Miami for two years, Thigpen wants a chance to play again.
Skinny: With 20 career starts, Gradkowski brings some starting experience. Size and arm strength have always been question marks. But mobility and experience in a West Coast offense makes him a possibility for two Ohio teams, with the Bengals being a more likely target.
