I edited to add he's from the Bill Walsh tree via Mike Holmgren.Who knows if Reid “came up with it”. My guess is well he’s an old dude. His philosophy has evolved through the years and incorporates multiple offensive inputs into what it is today.
So the branch we take from the Reid tree, if we do at all, should be one of those new growth branches. Not a branch from a decade ago.
The West Coast Offense.
And yes, somebody to implement a modern, innovative version of it, please.
