Schaub is going to hand the ball of regardless of what zone blitz schemes the Patriots want to show early. The Patriots will sell out to stop the run. Once that is a confirmed component of that side of the game you'll see Schaub gamble down field with Johnson a bit. The Texans have nothing to gain by exposing Schaub and they won't. If the Texans win it will be a close low scoring game, so the outcome will be determined elsewhere.
With Vince Wilfork, the run is already nearly dead anyway. Believe me, Bill Belichick isn't going to do anything exotic here. The key for NE is hit Shaub often & disrupt Houston's WR's & TE's off the line of scrimmage. Eventually, Schaub will see LB's & DE's bearing down on him even in time outs.
