The steelers have 343 points, and we have 295 points. So, I think a case can be made that they have made better use of the yards they have gained. Whether that is coaching, players, or some combination thereof can be debated.
But, the big difference between the Steelers and Texans is on defense, where they have given up 227 points to our 317 (and that is after our giving up 5 points the last two weeks)
So they have scored 50 more, but given up 90 less, yet I haven't heard Mr. Biped call for the head of Fangio. I find that a bit interesting.
