Gene, I think you are severely underrating Foles with that post.
Foles is much more mobile than Glennon. Foles is much better at moving in the pocket and outside the pocket to make throws (as opposed to running). He is also a better runner… he rushed 57 times for 221 yards and 3 TDs this season, compared to Glennon’s 27 rushing attempts for 37 yards and 0 TDs. Foles also turned the ball over much less often.
