Notre Dame have officially fired Head Coach Charlie Weis today after a 6-6 season with the Irish. Weis had ND's offense clicking all year, but like Michigan, defense was the problem for most of the season.
Anyway, the reason I'm posting this is because a change in Head Coach at a program like Notre Dame has a huge impact on recruiting. Recruits who had built a relationship with Weis now find that worthless, as he'll probably be somewhere in the NFL, rather than at ND.
The main recruit this involves for Michigan is four star safety Sean Parker, who has ND and UM in his top four schools. He should be visiting Michigan this winter. Parker has stated he will have to get to know the new coaches, "It would have to start all over, because I would have to get to know the coaching staff like I did with the staff they have now."
