There are two prominent philosophies when it comes to running the ball in my opinion; Zone / One Back and Block Down & Kick out.

 

Zone concepts typically don't use a Fullback but almost always include a Tight End in order to widen the blocking surface, the span of the Linemen who are in close proximity to one another, in order to create space for the Runner. The idea is that every front that the Defense presents will have holes / gaps but those gaps won't be visible until the play is in motion. The OL step with the direction of the play, block the closest DL, then peel off to take a LB as needed. The RBs are taught to read the first D Lineman playside, then the next inside LB to take the hole that opens up. A key to this is lateral movement by the RB at the snap. His sideways movement moves the Defense and helps to open up lanes. You can pull in this Offense, but often times it's a "fold" type of pull where the OL leads up through a gap to seal off a LB.

 

Block down and Kick out is really kind of the opposite. The OL blocks away from the play, leaving an unblocked Defender for the FB or a pulling OL to take. For a play to the Right, the OL will look to their Left to seal the inside where the FB looks to take the first bad guy to show on the playside. The RBs are taught to read the FB's block and cut inside of him or to whichever side he is sealing.

 

Thing is, don't run what you can't coach. And right now, it looks like whatever they are running they aren't doing a great job of coaching it.
