While I agree that the timing sucks, I cannot blame Brian Kelly for bolting. This is a dream situation for him and his family. Being the head coach for Notre Dame is big. The upside is huge. He goes undefeated at Cincinnati and gets to play in the Sugar Bowl, but not a national title. He goes unbeaten at Notre Dame and he's playing for all the marbles. Plus, I'm sure he is getting a large raise.
This is a guy who six years ago was coaching the equivalent of UM-Duluth. Heck, five years ago he was leading Central Michigan to a 4-7 record. And, now Notre Dame calls??? Seriously? I mean you would have had to have gotten a million-to-one odds in 2003 that the coach at Division II Grand Valley State would get offered the ND job in 2009. How can you blame the guy when the largest name brand in all of college football offers you a job? Again, the timing sucks, but he has to take that job, IMHO.
Think about it in terms of your own job or profession. If you are successful, but someone came along and offered you a better job (ND certainly is that), for probably double the pay (making you a millionaire several times over), have a better chance for professional achievement, at a place that is the most well known namebrand in your profession while you are only six years removed from being a complete non-factor in that profession? You have to take it no matter how crappy the timing is.
