Has there ever been a better example of the grass isn't always greener on the other side? When Brian Kelly was still leading the Notre Dame football team, he had it made in the shade. People in South Bend loved him and he was 113-40 during his time with the program.
He was able to get Notre Dame back on the map, which was awesome. However, he bolted on the Irish to take the job at LSU, claiming he wanted to go to a place where the resources were available for him to compete for a national championship.
