It is an option-based offense like the Wishbone, but
the formations are very, very different, and the personnel. At Oregon, all plays were in shotgun, and in spread formations, usually with 1RB/1TE/3WR or 1/0/4. In Philly he’s introduced a few plays under center and is using TEs a lot more (though often split wide or in the slot), but it’s still a spread in place of the 3/1/1 of a wishbone.
Because of the formation, the passing game is a dramatically larger threat than in the Wishbone, and his teams can and do throw the ball effectively.
It uses zone blocking, whereas the wishbone used man blocking. Lighter, nimbler linemen who use technique in run and pass game, in place of the road graders.
The Wishbone’s core play, the triple-option veer (FB up the gut, QB keep, or pitch to HB) had a single play side; you were going either right or left. The core plays of a zone-read offense threaten BOTH sides of the defense. Especially if you have a mobile QB, the defense can see the line going one way, the back going that same way … but still have to defend the backside.
Extensive use of “package plays” which have run and pass options on the same play. These videosare really good, and accessible. Everything else he runs is designed to set up either Inside Zone Read or Outside Zone Read.
This isn’t really accurate. Neither the Chargers nor the Chiefs locked down the Eagles. Turnovers have been a major issue for Vick and the Eagles, that’s not scheme, it’s a careless and inaccurate QB. Their receivers have also been playing poor. They got the one-on-one matchups the offense wants and relies on, but the wideouts haven’t been winning those matchups enough. Again, players not scheme.
The offense worked so well at Oregon partly because the players were usually just better than their counterparts. They really only lost when their offensive line got beat in the trenches (vs Alabama and Stanford).
Running no huddle to generate and exploit matchups isn’t new. I’m not sure what people were expecting. Packaged playcalls were coming anyway, too.
What I like is that Kelly isn’t not trying things just because conventional wisdom says they won’t work.
Also, it is the first year. Let them get some time and players under them to run the scheme and we’ll see. Of course, by then, the whole league will have caught up.
