From sources with connections inside the Notre Dame hierarchy:
"No F#$^&*g way!"
That's a paraphrase of my friend's reaction to the ND/ACC gossip. He said "for sure" ND fans will not support this affiliation and many influential alums will work to stop it from even starting. In fact he said many ND fans like the proposed BE bb school additions of Marquette and DePaul to bring a "midwest flavor" to the schedule.
Another source added:
"Old news! The rumor is the same deal that remains on the table w/the Big Ten--which would be the preferred associate relationship to most ND fans."
