Here's the more classic example of a pulling guard, and Packers LG Justin McCray (64) gets practically the equivalent of a three-for-one. His assignment is pull to his right and take on LB A.J. Klein (53) in the hole, which he executes. But watch also as CB Ken Crawley (20) comes crashing in from the right side, trying to beat WR Jordy Nelson's block. McCray's leg actually gets a piece of Crawley just before he engages with Klein. On top of that, LB Manti Te'o (51) is clearly reading the pulling McCray as his key and overpursues, taking himself out of the play as the huge hole opens for Jones.
