NBC has covered Notre Dame's home games since I believe, 1991. When they had AFC football (up until the end of the 1997 season), I think that they also used their lead broadcasting crew (e.g. Dick Enberg-Bill Walsh). I believe that they rotated crews during the AFC era with Dick Enberg, Tom Hammond and Charlie Jones taking turns on play-by-play. More recently, they've used Tom Hammond and Pat Haden (who was also their lead Arena football crew for some time). Cris Collinsworth also called some games.
