As usual, the Philadelphia Eagles will enter the upcoming season with major question marks at the most important position in professional sports: quarterback. In fact, it's really not a stretch to say that the entire season for the Philadelphia Eagles is banking on the twice surgically repaired left knee of quarterback Sam Bradford.
It's impossible to know what to expect from Bradford. Will he be the dominant presence he was a few years ago when he won a Heisman Trophy at Oklahoma and Offensive Rookie of the Year with St. Louis? Or will he be the player who failed to develop since his rookie season and suffered a season-ending ACL injury in both 2013 and 2014?
