Cassel signed a two-year contract with the Vikings this offseason. He's started 62 games over a nine-year career, most notably helping the New England Patriots to an 11-5 record in 2008 after Tom Brady injured his knee in the season opener. Cassel went to the Pro Bowl in 2010 after a 27-touchdown season with the Kansas City Chiefs, but has been pedestrian at best the last two seasons.
