Some more random numbers. These are from PFF:
Steelers: Pass Offense, 30th (51.7)
................Pass Blocking, 32nd (28.7)
................Run Offense, 25th (63.8)
................Run Blocking, 29th (51.0)
Texans: Pass Coverage, 10th (78.3)
..............Pass Rush, 31st (56.9)
..............Run Defense, 32nd (32.3)
*************************************
Texans: Pass Offense, 18th (66.8)
..............Pass Blocking, 20th (59.7)
..............Run Offense, 26th (63.4)
..............Run Blocking, 12th (63.2)
Steelers: Pass Coverage, 13th (74.2)
...............Pass Rush, 4th (81.4)
...............Run Defense, 17th (63.0)
One humongous outlier I don't understand is the Texans Run Blocking grade. Weird.
If the Texans can slow the Steelers pass rush, it should be a pretty even match up.
Going out on the limb, I'm predicting an upset Texans win.
