That is on Jameis. Snow is running a double mug read blitz with Chinn and Shaq. Whichever way the center blocks, the opposite backer blitzes and the other goes out into coverage. We have 6 potential rushers on the line of scrimmage and Jameis has 6 blockers - everyone has to get a hat for a hat. Whether it be half slide, full slide or big on big and get the RB on a linebacker, it doesn't matter. He has to assign him where to block or send the running back on a hot route.
This was a great move on Snow. Don't change it up if it's working.
