I'm going to start by saying NFL Rewind kicks ass. Anyways I was re-watching the game, when I noticed something interesting on the sack safety play. I remember in the gameday thread someone talking about how the Guard was always move before the snap and why wasn't there a false start called on him all game long. The answer to that is the Guard is allowed to tap the center in shotgun formations before getting "set". This allows the Center to prepare to long snap without having to look between his legs to see if the QB is ready. This prevents possible injury to the Center, and allows him to watch the D better before the snap, it's also a staple of the hurry up offense. This is key to this play, and the person who makes this play is Antonio Smith. If you rewatch the play you'll see the Center and the Oline calling out potential blitzers and having people set up their blitz pickup. The Guard then taps the center. AS SOON AS this happens, Antonio Smith shifts to the right and completely throws the entire offensive line out of it. The left guard was supposed to shoot outside and take Barwin, but instead gets swallowed up by Antonio Smith. Mercilus and Watt Run a stunt, with the RG having his hands full with Watt the RT tries to follow Mercilus but Watt gets in the way (Watt also jumps into the air and you can see the RG and RT freak out). The center who was the most confused by A. Smith's shift barely touches Mercilus as he rushing in through the center and he would have had the sack if Barwin didn't. On the pre-snap read, you can see the Center pick out Bradie James, I'm pretty sure he called for the RT to pick him up because it looks Barwin is going into coverage (judged by him walking behind 53 pre snap, but Barwin moves back after the Center Tap) James however runs a stunt with A. Smith and the LT tries to follow him inside letting Barwin sneak past him. Basically the pre-snap tap allowed the Texans to show one look to the offense and then drastically change it in that one second interval before the center snapped the ball, resulting in confusion and victory. A. Smith pretty much takes out the entire left side of the line and left the center in lala land. Hopefully 76Texan can contribute some pictures.
