Terminology: Big-on-Big

7 Jan

Also known as  BOB, Big-on-Big is a six-man – 5 OL and 1 RB – pass blocking scheme that matches offensive linemen against defensive linemen.  In other words, big guys on big guys and for the obvious reason: they’re about the same  size and strength. 

This allows the running back to block a defender more his size: a linebacker or defensive back, should they blitz.

If the defense doesn’t blitz, though, the running back is free to release into a pass route.  This assignment is called a “check release” because he checks first for a blitz before releasing. 

In the pictures below, big guys are blocking big guys and the running backs are checking for a blitz, but there is none as the linebackers are dropping into coverage.  So, once they see how the underneath coverage is developing, they’ll attack the open grass and give the Quarterback a checkdown option should everyone else be covered.
