Michael Vick and Nick Foles have different styles, yet run Eagles offense to similar success

Michael Vick is the speedy, elusive, strong-armed quarterback. Nick Foles is more of the classic pocket passer.

Despite obvious differences in the skill sets of his top two quarterbacks, Chip Kelly insists the Philadelphia Eagles run the same offense no matter which player is under center.

"We do the same things offensively with Nick that we did with Mike, and I think that's the beauty of those guys," Kelly said. "There are some things that Nick does different than Mike does. But it's not like we're going to be an I-formation team if Nick's in the game."

Foles will make his second straight start Sunday when the Eagles (3-3) host the Dallas Cowboys (3-3) in a battle for first place in the NFC East.
