This game, and really playoff run by the Eagles, should put any questions to rest as to the extent that a scheme/game plan can enhance a QB's play.
The Eagles play-calling was masterful throughout the playoffs to help scheme up easy throws for Foles, keep defenses off balance, and manufacture big plays. Foles made some great plays, sure, but I saw more creativity within a single Eagles drive than I've seen out of our offense all god damned season.
Dak isn't perfect but I damn sure wouldn't pass any sort of final judgment on him until I saw him play under a different, more competent staff.
