Eagles beat writer Jimmy Kempski of the Philly Voice:
Anytime a tight end made any kind of impressive catch, it always seemed to be Zach Ertz. He was very active, and is already becoming one of Sam Bradford's favorite targets. Ertz has said that he wants to be the best tight end to ever play the game. While that is obviously a very lofty goal, I feel fairly ceretain that if the Eagles play him as much as they should this season, he's going to put up big time numbers.
That's the rub with Ertz: Thus far, the team has limited his snaps to keep Brent Celek on the field due to his superior blocking. Ertz was the #13 TE in both standard and PPR formats despite only playing half of the Eagles’ snaps in his second year. Ertz played mostly (73%) on passing downs, so if his playing time is going to increase, a majority of the additional snaps are likely to come in run formations.
