Unlike ND, they have a means to fill in recruiting holes after the fact. They will not have a ND circa 2007 problem where they are 20 players down and almost devoid of all Sr and 5th year Sr players.
It will not be as good for them as having signed the recruits they originally had, but there are a lot of juco players that walk in the door ready to play SO and JR year to fill in holes for them.
