There are plenty of players and coaches from many sports who win a lot every year and are as good as it gets but can't quite 'win the big one' sometimes like Michael Jordan they explode after getting over the hump or sometimes they never do like Charles Barkley. Messier anyone? Steve Young? The list goes on and on, there is so much luck that goes into winning a championship that it can trump skill like Frattins team against Michigan.
It's still Und and Hakstols career record is awesome. It'll happen eventually.
