Look no further than quarterback Nick Foles possibly taking over for Michael Vick as the Eagles' starting quarterback.
A potential move under center will help the Eagles' brass determine whether or not Foles is indeed the quarterback of the future. Fantasy owners will have a much different agenda in evaluating Foles' performance, however.
Vick's status as a must-start in all fantasy formats is cemented with his ability to escape the pocket and run the football. But the question would suddenly shift to how Foles would perform utilizing the same weapons, behind the same porous offensive line.
Should Foles take over as starter in Philly, is he even worth a roster spot on your fantasy team?
The Eagles should be relying more on the running game right now anyway. But if Foles is planted into the starting lineup, look for Andy Reid to mitigate the rookie's exposure by utilizing LeSean McCoy and Bryce Brown much more out of the backfield.
Vick's ability to scramble adds a unique element to the Eagles offense. With Foles being a traditional pocket passer, that threat vanishes and allows opposing defenses to spend less time scheming toward stopping Vick.
Take away Vick's legs, and he becomes an average-at-best fantasy quarterback—even with the weapons surrounding him on the field.
With the inexperienced Foles being one-dimensional, his fantasy value would be pretty much nonexistent should he take over the reins in Philadelphia.
