Notre Dame is aggressively speaking with candidates, but they’re not particularly rushed in coming to a decision.
Names that have been either initially looked at, contacted, vetted or offered, include Malchow, Morgan, Suddes, Dawson, Miller, Pantoni, Thomas, Heuke, and LaFrance. (In addition to Blanchard, of course.)
At this time, Notre Dame is deciding between splitting the department at the top, or going with a single GM. Since the roles are so different between recruiting/portal/NIL, Notre Dame would prefer a split top end.
