The issue with a super high rate of 6/7 OL is that now that the tape is out, better defenses will just send extra PR/blitzers. Plus teams will start to learn the protection rules the Texans are using. Schematic "advantages" like this don't last that long. Not to mention 49ers really don't have anyone on their DL who can win one-on-one regularly. So need to see if how they perform versus defenses like Denver, Buffalo, KC, Chargers, and Indy x 2. As of right now Texans have to win 2 of those 6 games to sniff a playoff spot, and 3 of them to probably lock it up. I'm assuming wins vs Jax, Ten, Ari, and LV where the defense should be able to control the game enough to win even if the offense reverts backwards somewhat.
