Using your logic, our run D was what 122nd in the nation, giving up 223 yards a game (or something absurd like that)? So, WV will be able to run all over us. We'll be playing from behind, and our running game won't be a factor. Instead we'll be forced to play catchup which frequently means relying on explosive pass plays. Oh, but, we are gearing up for that power running game because we haven't the confidence in our passing game - unlike WV's passing game. That means their DL and our run game, as you point out, won't win us the game. It especially means that we will not blow them out with our running game if the bbestie running game can do is exchange blow for blow.
Further more, if we can improve, they can too. They took steps to improve by adding experience, depth and talent to that DL. We're not certain what they have. We aren't blowing anyone out based on the stats and star ratings, nor last year's rankings.
So yeah this will be a dog fight and a hard fought win for UT. But, nothing worth being cocky about. We can tart strutting when we have a winning streak against every team in the SEC, rather than a losing streak against every team. Each win will help our confidence, and will get us closer to being rightfully boastful. But as of now, we have a lot of work to do. The team, I expect, will have that mind set, and the fans should too.
