I don't know. Seattle, Baltimore, and Giants have similar approach and they have had postseason success.
It is about being effecient. That is all that truly matters
In Baltimore, Kubiak runs a successful stretch-zone run scheme. Yes, it is designed to run, to set up the pass. But the philosophy is eventually get large chunk yardage.
In Seattle, Bevelle fluctuates between working off the play-action to capitalize large gains and a traditional West-Coast offense.
Ben McAdoo in New York runs a hybrid west coast scheme and vertical attacking offense. which has not proven very effective.
How would you describe Shula?
