I understand 'stretch zone' is what they're running in Jacksonville too. I honestly wasn't aware Kubiak was using it, though I assumed zone blocking based on his scheme.
And although we haven't really discussed it, a zone scheme might go a long way toward fixing our vulnerability to 3-4 defenses.
That, and you can basically plug in any RB and have them be effective. Pick a hole, make your cut and hit it hard.
