Houston Right Ace RT O2 Dive is an attack on the heart of the defense.  Vs. 4-3 and 3-4 the Center and the left Guard have a quick double on the Nose, from there the Center rubs off and works up on the Mike.  The Right Guard drive blocks the LDT. The FB is in the 2^nd Te position and he blocks the Wil backer.  X runs the corner off, while Z has a cross field block on the near Safety.

Vs. the 4-6 Bear defense the blocks are slightly different.  Since the Center and both Guards are covered, they have to get their defenders shoulders turned away from the play side A gap.  The play side Tackle has a wrap around block on the LE, while the TE has a drive block on the Mike.
