Donovan McNabb thinks the read option 'is just a fad.' (USATSI)
Donovan McNabb has a lot of opinions. Of course, that's his job as an NFL analyst, one he feels he's perfectly positioned to offer given his his 13-year career, 11 of which were spent with the Eagles.

Which brings us to the Week 3 Thursday-night matchup: The Chiefs, coached by Andy Reid, the man who brought McNabb to Philly, will face an Eagles team now led by Chip Kelly.

In two games, Kelly's high-paced offense is averaging 31.5 points and 477 total yards. To watch this group is akin to viewing the game on fast-forward while the defense is stuck in super-slow mo. But McNabb's not convinced it's sustainable, despite Kelly's success running pretty much the same offense at Oregon.

“I don’t know if any offensive player would want to run 90 plays in a game," he told CSNPhilly.com. "If you’re running 90 plays in a game, that means your defense is pretty awful and you’re running entirely too many plays. At Oregon, [Kelly] may have ran 75 plays in a game, but you’re not going to run 85, 90, not in the NFL, and teams and defensive coordinators are a lot better than what you’re going to see in college.”

After hearing McNabb weigh in on Robert Griffin III, Matthew Stafford and his own Hall of Fame chances, we reflexively dismiss him. But he has a point about Kelly's offense.

The Eagles' defense is awful. And NFL defenses are bigger, faster and smarter than your run-of-the-mill Pac-12 team.

McNabb also has the same concerns we voiced after the Eagles' Week 1 beatdown of the Redskins: Can quarterback Michael Vick and running back LeSean McCoy stay healthy in an offense that regularly exposes them to big hits?

“It’s not so much Mike, I think it’s all the guys,” McNabb said. “You worry about the depth, you’re worried about the injuries and long-term. Right now, everything looks great, but I’m just worried as this thing continues. Week 8, Week 9, Week 10, if guys get hurt, who’s going to step in? What guys do you have to fill in in these key roles?”

So what's the solution?

“I tip my hat off to what they’ve been doing the first two weeks, but there comes a time if you’re up by 14, up by 21, maybe with about 11, 10 minutes to go, it’s time to go into a mode where you’re trying eat up some clock,” McNabb said. “You can’t continue to run that fast-paced offense because it continues to run down not only their defense, but it wears your offense down, too.”
