Here comes the Mario slurping. Anyone ever thought that Auburn is just mediocre? That's a way more likely conclusion than Mario magically becoming a solid game day coach. He's a great "recruiter" and while he should be able to out talent most of the Pac-12, guys like Petersen and Shaw will work him when it matters. I wouldn't be shocked if he found a way to lose to Leach if they see each other, just because he's so mediocre in regards to basic game management.
Having a legit franchise QB also helps, one that was willing to come back and play one more year. I will say this, the proof in regards to Mario will come next year when Herbert is gone. Let's see what happens. I think that eventually he comes back to what his ceiling is at a wealthy program: A 9 win, middle of the top 25 coach that finds a way to do less with more.
