Al Golden won the award, but I thought this was interesting.

"The other four finalists were Arizona State offensive coordinator Marcus Arroyo, Indiana defensive coordinator Bryant Haines, Tennessee defensive coordinator Tim Banks and Texas defensive coordinator Pete Kwiatkowski."

So of the 5 finalists, Ohio State beat 4 of them
It's also interesting 4 of the 5 were defensive. In an age where offense rules, maybe defense is coming back around.
