That's true and last night didn't demonstrate he can recruit amd develop recruits, as he must to compete with Penn State.
But of course given the timeline it wasn't possible for him to have demonstrated that this weekend.
What he did do was show that he can get the most out of a roster, which at a school with that tradition and that commitment to getting back to the top will translate to him being the most likely coach to challenge Penn State since 2011.
Doesn't mean it's going to happen but based on what I saw this year I think the odds are better with him than for Nebraska, Iowa, or anyone else.
