Bear crawling through the o-line

CoachBR91:
My old team used to see a lot of double wing formations. We taught our guys to bear crawl through a combination of the A/B gaps. Usually to the side the WB or FL motions to.
In a 4 front, we'd have the interior lineman (DT's in a low 4 point stance) crab/bear crawl through and tell them to keep their head up and just grab the first set of legs they came to. The idea is to majorly disrupt and throw off the timing in the backfield. The double wing, if run correctly is largely based on timing. It is a Wing-T set. If you can get your guys through and disrupt that timing, the offense is going to have a hard time executing. Watch out for the counter though if only stunting to the motion side. If your in a 4-4 or 4-3 defending double wing, I have always taught my OLB'S the golden rule as: if motion comes to-you go thru ---motion goes away-you stay----you have to have the OLB's step up and blow the play up when motion comes to their side. If motion is away, sit and read. Hope this helps. It's just the way I've done it in the past with success. I'm sure others have had success using other set-ups.
Good luck coach.
