The dynamic has shifted, and that could mean a spot on this team for Trent Edwards.

Coming into the preseason, each quarterback had his defined role. Michael Vick would be the starter; Mike Kafka the developmental backup with a couple years in the system; and Nick Foles the rookie unknown who would watch and learn and hopefully show some promise. Edwards, struggling to complete balls to unguarded receivers in practice, was an afterthought.

What no one accounted for was how well Foles would perform. He has become the story of the preseason and has earned the No. 2 spot behind Vick. The 6-6 slinger has stolen not just the backup spot from the injured Kafka, but also the title of the primary developmental quarterback in the system. If the goal is now to not just serve as a viable emergency option but help shepherd Foles along, then Edwards  might be the better choice.
