Waaay back when Urban was coaching my alma mater...BGSU...he was rumored to be a serious candidate for the MSU gig. In the end, they didn't want to roll the dice on a guy with two years in the MAC as his sole head coaching experience, so he baled on us for Utah. When you look at his record...winning huge in three distinctly different regions of the country..he has to be considered one fo the all time great coaches. Who else can make that claim? But..someone with his baggage is exactly hat MSU does NOT need right now.
If you want a former BGSU coach...look at Dave Clawson down at Wake Forest. He's basically on a lifetime deal there so he might not be interested, but he's smart, disciplined and recruits extremely well.
Another name to consider who might be easier to poach is Colorado OC Sean Lewis. Did well as a HC in the MAC and that Colorado offense looks good
