Re: UNC's PLan
It means simply that, like every other inside zone read package in the country, the QB options a DL on the backside. In this case, if Clowny crashes on the inside run, the QB pulls the ball and runs through the area vacated by the DE. If he plays the QB run, the QB hands off to the RB. That read is sometimes referred to as blocking the DE with your QB. You guys run some of that, too. No?
If you Google "Chip Kelly's Offense", you'll find a site run by Oregon fans that breaks down those basic zone read plays with video. Not exactly the same offense but the basic concepts apply.
