Dennis Dixon may be considered a long shot to earn Philadelphia's starting quarterback job -- or even a spot on the team's opening-day roster -- but he does have one advantage over fellow Eagles QBs Michael Vick and Nick Foles.
Not only he is the only one of the three who has played under new Coach Chip Kelly's system, but Dixon excelled in his spread offense at the University of Oregon.
With Kelly as his offensive coordinator in 2007, Dixon was in the Heisman Trophy conversation -- passing for 2,136 yards with 20 touchdowns and four interceptions to go with 583 yards and nine touchdowns on the ground -- before a torn ACL ended his senior season prematurely.
Dixon was drafted by the Pittsburgh Steelers but started just three times in four seasons with the team, with another knee injury wiping out almost all of his 2010 season. He spent last year on the practice squad for the Baltimore Ravens before signing a two-year deal with the Eagles on Thursday.
