Current Team: Baltimore Ravens
Status: Unrestricted Free Agent
Flacco has been struggling for years now to prove he's an elite passer, but he always seems to come up short in big games. He's led the Ravens to playoff appearances in all five seasons at the controls.
In 2012, Flacco had his best yardage total and lowest interception percentage of his career. Once again, however, the Ravens weren't good offensively in a lot of big games.
The playoffs will determine a lot about Flacco's value as a free agent, but he figures to be the best available in a very thin market.
Baltimore Ravens, Arizona Cardinals, Buffalo Bills, Kansas City Chiefs
Baltimore can make quick work of this with a franchise tag, but if the Ravens have another big failure in the playoffs, they may elect to go in a different direction at the position.
If they allow Flacco to hit the market, look for the Chiefs and Cardinals to show the most interest. Both teams are starved for a successful quarterback. Arizona will have Kevin Kolb coming off their books, as well.
In the end, Flacco ends up back in Baltimore on the franchise tag playing for an extension in 2014.
