From Pro Football Focus:

Out of all the offensive lines in the NFL, the Eagles currently have the fewest holes. Their biggest question mark heading into 2017 is center Jason Kelce, who is a former PFF All-Pro (2013) in his own right. They also have dominant players like Lane Johnson, who was the best right tackle in the NFL a season ago when on the field.

I agree that the Eagles’ offensive line is shaping up to be at least decent (and deep), but Pro Football Focus is making some assumptions about Jason Peters and Jason Kelce, who has flat-out not been good the last two years. I wouldn’t count on their production being what it once was.
