The Eagles offense presents different challenges, however. For one,
they have the best offensive line in football, so not having that extra run defender in the box could prove costly. Two, Jacksonville’s RPO’s — at least the RPO’s it used in the AFC title game — did not attack the Patriots downfield like Philly’s will. The Jags used the kind of RPO’s Kelly was using back in 2013, which are based on a pre-snap count of defenders in the box — the kind of RPO’s NFL coaches figured out how to defend a few years ago.
The Eagles will offer a fresher challenge — one, as Ertz noted, at least
partly orchestrated by Stoutland, a Kelly-era holdover who jumped to the NFL from college …
where he coached for Nick Saban at Alabama. The Patriots haven’t seen anything quite like the Eagles’ attack this season, and Stoutland surely will come into the game with a few thoughts on how to keep it fresh — and Saban-proof.
