Given Philadelphia's defensive overaggressiveness, have to think the gameplan involves a fair share of rub routes and double moves. I look no further than the most recent Giants(!) game and Rams game for evidence that this can be a successful plan offensively. It honestly is why Atlanta lost badly, as Sarkisian choose consistently slow developing plays, with obvious dino stems, making it one of THE worst gameplans I've seen.
Defensively, RPOs specifically: In the NFCCG only 14.3% (9/63) of offensive snaps were RPOs for the Eagles, with a 5:4 rush to pass ratio within those (gaining 3:2:8.3 yards within each respective option), within six formations, none attempted within either 20-yard line, and notably most on an early down. Hopefully, the nickel can come up big (Flowers, Brown, etc.); got to stop Blount and Ajayi (Clement concerns me on wheel routes, so while he applies, it's a different aspect of their offense, hence a separate mention) so that an extra (seventh) man won't have to be committed to the run. It's why I believe the Eagles get a fair share of scoring, but not quite enough given the CRITICALLY important increase in rush defense quality of late.
