With all of the speculation that Harbaugh to Michigan is a done deal, I thought I'd look up Urban's career record in rivalry games. It's better than I even thought it is. (Straight from UFMs profile on tOSU website-I did update the overall record and his record against TTUN, as the website still had it at 2-0)
His teams are 23-3 in "rivalry games." Bowling Green was 1-1 vs. Toledo; Utah was 4-0 vs. Utah State and BYU; Florida was 16-2 vs. Florida State, Tennessee and Georgia; and Ohio State is 3-0 vs. Michigan
Bottom line, is that whether JH comes or not, Urban get's the importance of rivalry games, especially The Game. JH coming to AA just means the focus and intensity going into The Game will be taken up a notch or two.
