Tight ends Zach Ertz and Josh Perkins were also very involved with the passing game as well. Ertz was a go-to target for Foles in some critical situations at every level of the field. Perkins saw a lot of extra snaps as well, particularly after Mike Wallace went down with an injury.

Why didn't rookie Dallas Goedert get more reps? Pederson was asked about it in his postgame press conference. This is my best guess at translating the answer he gave (he couldn't completely dive into all the details in his response).

Not all 12 personnel groups (one running back, two tight ends) are created equal.

There are different variations of 12 personnel on every team. Look at the 2017 Philadelphia Eagles. You have one 12 personnel look where the grouping is LeGarrette Blount, Zach Ertz, and Brent Celek. You may have another that's Darren Sproles, Ertz, and Trey Burton. Those two groups look the same in a playbook (RB, TE, TE) but are obviously different when you actually see them on the field. One of them indicates run, and the other one suggests pass.

You're going to have a different set of plays in the weekly game plan for each grouping. So from Wednesday through Saturday during practices and walk-throughs, each personnel group works on its package of plays for that given game.

When the team lost Wallace, it was left with a receiving corps that included Agholor, Shelton Gibson, Kamar Aiken, and DeAndre Carter. This was in a game where the Eagles were down early, and were forced to go a bit pass-heavy with a limited receiving corps. One of their best pass-catching running backs (Sproles) was not playing. The Eagles' 12 personnel group that is geared toward the pass game features Ertz and Perkins. That grouping, most likely, has similar route concepts that the 11 personnel group has in a given week's game plan.

Perkins is 6-3, 223 pounds. In theory (and I haven't studied his college film so I can't speak to how he was used there), he can do similar types of things that Trey Burton did for the Eagles last year in terms of his size and athleticism. I can envision a scenario where, in this 12 grouping, he's listed ahead of Goedert, especially if you're not trying to throw much on the rookie's plate with a heavy playbook week in and week out.
