Just got the July 12 SI in the mailbox. Tim Layden excerpts some of his upcoming book Blood Sweat and Chalk as an SI Obit for Don Coryell. It's a good read.
Layden attributes the visual (as opposed to random naming) play nomenclature to Coryell. A play call like 'I Right Omaha' becomes 'R 428 H Stop' - where each number is a distinct route for the respective X-Y and Z receiver. This system is in wide use today due in large part to Coryell. I'm not sure of the scheme Michigan is using - but one of the big plusses Coryell stressed with this system was the relative ease in which a player could learn the 10 or so routes and run the offense.
This made me wonder about the Michigan playbook. Every season there is at least one article about what percentage of the book is in play at any time. Mostly this is due to the inexperience and unimaginative play calling at times (Question: How many times can DR run the QB keeper? - Answer: As many as it takes before the Hawkeyes actually stop him.) I've never heard RR or any player call a play by name. I wonder how complicated the playbook itself is. Given the learning curve - I'd say pretty complicated.
The article doesn't mention the 82 overtime playoff game between the Chargers and the Dolphins. All time best game I have ever (ever) seen. Never will there be a TE as dominant in a game as Kellen Winslow was in that one. Thank you Don Coryell for showing us what a TE can be.
There is not much to crossover with Michigan scheme wise anymore I guess...but this is a good article. Check it out. (DreadlocksFast was able to find the link.)
One last little tidbit - Joe Gibbs says in this article "No matter what you have in football you need something you can do really well and run it over and over again." For Mich 2007 that was run Hart behind Long. For Mich 2010 its Denard running zone read (IMO).
I know TL;DR...
