Taking a look at 2013's free agent quarterbacks, plus potential cap casualties
Joe Flacco is the cream of the crop of this free agent class. Coming off of another solid regular season capped off with a stellar postseason and Super Bowl MVP, Flacco made the right decision by turning down an extension last summer. Though he is set to be an unrestricted free agent, it's hard to see him signing with a team other than the Ravens, even if the process is long and strenuous.
There's not really any desirable starting-caliber talent in the rest of this group. Matt Moore is a very solid backup, boasting an 80.5 career quarterback rating, but his phone won't be ringing off the hook with GM's offering starting jobs.
Tarvaris Jackson will be an interesting player to monitor, as everywhere he goes he impresses coaching staffs in practice, but struggles to show the same ability on game day. If he ends up with a coach who can find a way to unleash his talent, he could end up getting another shot at starting somewhere. Chip Kelly's Eagles would be an interesting landing spot.
As a Raider fan, I know that Jason Campbell can be a great backup quarterback. With solid protection and a good running game, Campbell can run an offense very efficiently. It's unfair to judge him off of his 1.5 starts with the Bears last year, because he was standing behind a horrendous offensive line and essentially had one effective receiver to throw to. A contender would be lucky to have Campbell as insurance, but I could also see a team like the Jaguars picking him up to compete for the starting job over the summer.
Big names Vince Young and Brady Quinn will be on the market, but after Young was dumped by the Bills before the start of the regular season and Quinn went 1-7 as the starter in Kansas City, there's a chance no one will even want them.
After losing the No. 2 job to Kirk Cousins in Washington, Rex Grossman was forgotten about by most people. With a 13-3 record in his only full season, a team may bring him in as a backup.
Byron Leftwich was once solid, but looked bad in his two games last season... Matt Leinart got significant playing time in one game in 2012, but looked pretty terrible... Josh Johnson is an interesting player as an athletic quarterback... David Garrard hasn't played since 2010, but claims he is healthy and may get some looks.
