There are only a couple of really different schemes run in the NFL. The Air Coryell scheme is really a variant of the Sid Luckman offense of the really old days when passing first became en vogue. Then of course, is the WCO.
In the Coryell tree there are guys like Ernie Zampese, Kevin Gilbride, Norv Turner, Scott Linehan, Mike Martz, Cam, etc...the basic difference between these offenses is not really the scheme but the play-calling...Gilbride, Martz, and Linehan are more vertical, downfield passing with slightly longer routes and a little less conservative...
The Zampese, Turner, Cam style of play-callling is more of the shorter to intermediate routes that relies on a strong run game with the lead blocker being the fullback and slightly more conservative play-calling. They also like to use the TE in deep middle routes after the WRs and/or backs have cleared out the short field.
because of this, I am perplexed that Cam-Mul decided to dump McMichael. I suppose we'll see how it shakes out...
