For me Id call an RPO (run pass option). Inside or outside zone run with an audible to switch from one to the other. One wr in isolation (lawler) on one side and trips to the other side. He can run an option route where he either finds the soft spot in the zone, or runs a deep double move in single coverage. Thing about zone cover is if you run deep enough it becomes man or youre wide open. The isolation also helps to expose the Ds cover scheme to an extent (Instead of just with motion), or play a hybrid man and zone.
On the trips side if the defense stacks the box you can flex the TE (eli) out to wr and throw a screen pass with darvin, woli, and eli blocking. If they show Double or even S shade to lawler or play cover 3 you run the ball. You can even motion woli in for extra blocking or have him run to block a Lber. You can run portions or all of the snag concept in the RPO to create a quick high percentage throw on the 3 wide side. If the dbs stack up front you go over the top of them. If the HB/hbs stay deep you have a big screen play advantage.
If the D cheats to any thing with its alignment you audible to attack the opening. With a heavy line, and an un balanced split spread formation they have to give up some thing. Man to man on the iso, limited over the top on the trips, not enough bodies at the line for the screen, or bodies in the middle to fill gaps.
Normally Ds might have a complex scheme like rotating coverage, but in a hurry up that isnt likely, and if it happens it isnt as likely to be effective. Its hard to call that in at the line. Usually you see base defenses vs hurry up. Either blitzing or dropping.
The goal is to get an extra OL on the field that creates a miss match. But even running the hurry up with coverage line up dictating play call / audible can leave a D reeling. And with a guy like Eli who is a 2nd level monster with great mobility you have a considerable miss match vs the 5th DL in virtually any team.
You can also do that with out the OL and use woli as a regular flex TE. Sam is the hardest position on the field to play. Even the better sam lbers in the league arent guys you want in the box getting hit by a level jumping OL.
Blms production is a considerable product of his system. Reilly is a system changer. Hes a throw back qb. Id take him hurt over healthy BLM. Reilly doesnt rattle. He doesnt whine or cry or moan or blame his team mates first chance he gets. Hes a better arm talent and a tough SoB to bring down.
