Now that Kelly has officially named Vick the starting quarterback, it's worth spending a couple minutes thinking about one of this preseason's biggest mysteries: Why have the Vick and Foles offenses looked so different?

Vick, for the most part, has been handing off or standing in the pocket and throwing downfield. Foles has been running a bunch of hurry-up and all kinds of crazy read option looks that involve him lumbering around the corner or faking a handoff / running outside / firing a lateral to his WR at the sidelines.

It's almost as if the staff "knew" Vick (Foles) could run (pass), but wanted to see if he (he) could pass (run) ...

So if we assume we've really only been seeing one-half (or less) of the offense at any given time, what's our sense of how it will look once they're playing for keeps? I have my own theories, but in this case I think we can more profitably spend our time discussing the predictions made by one Anonymous J.

For the Eagles Almanac, Justin wrote the best thing I've read to date about Chip's time in Oregon and how it will probably translate to Philadelphia. He has also made a number of uncannily accurate predictions in other fora that suggest he's got some insight here.

In AnonJ's opinion, the real 2013 Eagles offense isn't showing up in the first quarter. Or the second quarter. Or the third quarter. It's late in the game, when most people have stopped watching, and Dennis Dixon is running the show:

And what does this offense look like? Pretty much just like Oregon. Lots of read option, lots of QB on the move, all that FishDuck stuff.

I'll point out that I have my doubts about all this. To me, the Dixon offense looks a little too much like pure-Oregon and not Oregon-as-translated-to-Philly.

On the other hand, I'm something like 0-and-a-bazillion on recent Chip Kelly predictions that have differed substantially from J's guess, so if we're taking bets, you should understand the headwinds.
