There are a lot of question marks surrounding the 2013 Philadelphia Eagles.
After all, just look at how the Eagles ended last season. They won three of their first four games, all of their victories coming in dramatic last-second fashion. But then they collapsed, losing 11 of their final 12 games, including an embarrassing eight-game losing streak that all but ended Andy Reid's tenure in Philadelphia.
From quarterback to offensive line to the secondary, the Eagles have a lot of work to do to become one of the elite teams in the National Football League, like they were during the majority of Reid's tenure as head coach.
It begins with quarterback, where the team currently has five on its roster: veterans Michael Vick and Trent Edwards, last year's rookie Nick Foles, former University of Oregon star Dennis Dixon and undrafted GJ Kinne. All are in the running for the 2013 starting job, as the Eagles will have open competition for the quarterback position.
With the free agency period and the upcoming NFL draft, the Eagles could enter the 2013 season with as many as five, six, seven or even eight new starters on their team.
