I don't think it's as difficult to reproduce as others do, but I don't think we should really be striving to try to win the game in the same fashion.
The TOP was so lopsided not simply because App was getting 3 yards every carry, but as you pointed out, A&M's offense was so bad. As I pointed out in my thread I started out earlier today, A&M had 8 possessions. One was a TD drive, another was their final drive of the game where they missed the game tying FG, and the other 6 drives were all 4 plays or less with the longest drive of these 6 only gaining 29 yards.
If their offense plays to that level against us, we will also more than likely dominate the TOP. Anybody would likely dominate TOP if the other offense was basically going 3 and out 75% of the time.
Another factor is that A&M housed a kickoff. Now it is no given the drive would have amounted to anything, but returning the kick for a TD skipped an entire offensive possession altogether. Maybe A&M goes 10 plays 75 yards and scored if the kick had been a touchback. Maybe they go 4 plays, 15 yards and punt. You don't know, but that kickoff return did take some plays off the board also, inflating App's TOP.
We should not be striving to get 3 yards per carry and hoping to reproduce the 3rd and 4th down rates App State had. We should be hoping to hit more chunk plays on offense. However, on defense, we 100% need to be striving to force A&M to have as many short and unproductive drives as App State did. If we do that, I love our chances in this matchup.
I have enough faith in TVD that I think our offense will have some success. I'm not saying we light up the scoreboard, but I think the offense will get theirs at points. I think this game really comes down to how much better is our defense this year compared to last, and how well do we contain their athletes. If our run fits continue to be great and we aren't getting burned over top, I think we have a very good shot at winning. If our personnel issues really begin to shine, then we may have a frustrating night ahead of us.
I really like our DL versus their OL, so that's a potential major advantage for us. If we dominate the trenches and keep their rushing attack bottled up, I'm not sure I trust any QB on their team to be consistent enough to beat us should TVD and the offense perform like we think they can.
