My feeling before this game was that the Texans would possibly start out testing their front 7 against our O-line, and not moving the safety up to stack the box against the run. My belief was that the Texans might want to see if their front 7 were able to handle our O-line, since there were so many questions about the line. That way, they could keep the safety back and potentially make things more difficult for JP.
Instead, it looks like the Texans started out the way everybody else expected, with the safety up to stuff the run. Looked like it worked, too. However, JP came through in the clutch and played well, forcing the safety back into coverage.
This, I suspect, is exactly what our coaches wanted, and the Texans obliged. The real test at that point, however, was to see how our O-line responded against their front 7. They delivered. Willis started getting some nice holes, the yards piled up, and the chains moved. Didn't result in TDs, but it was the type of ball-control offense we needed to keep the game out of reach.
So, my props to the O-line to the way they handled the Texans front 7.
