Monte Kiffin’s worst nightmare came true: He’ll have to face Chip Kelly’s offense twice per season now.

Kelly, who was hired Wednesday as the Philadelphia Eagles' head coach, schooled the 72-year-old Kiffin in the college game. Kelly’s Oregon offenses averaged 601 yards and 50 points against Kiffin’s USC defenses, with the Ducks winning two of those three games.

Kiffin simply never figured out how to stop Kelly’s zone-read-intensive spread offense. The most humiliating USC-Oregon matchup for Kiffin was the last time they met, when the Ducks rolled up 730 yards in a 62-51 Oregon win in November.

Oregon quarterback Marcus Mariota had 400 total yards in that game, completing 20-of-23 passes for 304 yards and four touchdowns and rushing for 96 yards on 15 carries. Oregon running back Kenjon Barner rushed for 321 yards and five touchdowns on 38 carries.

Sure, the Cowboys have a heck of a lot better defensive personnel than USC did. But you don’t reckon that LeSean McCoy, DeSean Jackson and Jeremy Maclin, among other Philadelphia offensive players, would look pretty good in those wild Oregon uniforms?

Oh, and Oregon isn’t the only zone-read spread team that lit up Kiffin’s defense last season. Unranked Arizona racked up 588 yards in a 39-36 upset over USC, when the Wildcats had a 350-yard passer, a 250-yard receiver and two 100-yard rushers. The Trojans weren’t at a talent disadvantage in that game.

It remains to be seen how much zone read the Eagles will run under Kelly. That will likely be determined in large part by whether he keeps Michael Vick – and whether Vick can stay healthy – or goes with Nick Foles as quarterback.

There’s little doubt, however, that the Eagles will feature a fast-paced offense. The Patriots, who picked Kelly’s brain and borrowed heavily from his system, had the NFL’s fastest average snap time at 24.9 seconds last season, according to ESPN Stats and Information. Oregon’s average snap time last season was 20.9 seconds.

Even if the Eagles don’t run much zone read, the Cowboys better get ready for it.

It’s a staple for the team they’re chasing in the NFC East, the Washington Redskins, although Robert Griffin III’s serious knee injury could certainly slow that down. Same with the Carolina Panthers and Cam Newton. The Seattle Seahawks and San Francisco 49ers, a couple of teams that look like contenders for years to come, also run some zone read with electrifying young quarterbacks Russell Wilson and Colin Kaepernick. And there are more of those dynamic dual-threat quarterbacks coming up through the college ranks.

The NFL game has changed since Kiffin’s legendary tenure with Tampa Bay. Unfortunately for him, it’s starting to look a lot like those Pac-12 teams that gave him so many problems.
