I think that's what most fans would like to see. At the same time, McGraw doesn't appear to be eyeing the exit and any year now Niele could opt to take a head coaching job elsewhere especially now that her son, Jaden, is pretty much grown (now a high school junior).
A fun wrinkle in that scenario is that Jaden has now picked up a scholarship offer from Notre Dame. You could end up with an inversion of the typical scenario where instead of the high school graduate going away for college he stays home and his mom goes away!
