Luke knew he was head coach for one year only. He's a great Buckeye and will be a great head coach, just not ready for the OSU quite yet. This year was a great little internship for him though. Some rumors flying that he's heading to Illinois, which I doubt highly.
But, regardless, any hiring by OSU would have been discussed with Luke first. I'm in the camp that wants Luke to stick around and be the HC sometime down the road when he's ready, because I like the guy, he recruits well, and is a great coach. Just not quite ready to be our head coach. I think there Urban and Gene Smith would at least talk to Luke about the possibility of staying around as an assistant.
