re: Is the ACC the biggest threat to the SEC's dominance?

Only if Miami, Florida State and Georgia Tech get back to late 80's and early 90's form. Oh Yeah Notre Dame would need to join for football and be the ND that they were under Holtz from 1988-1993 or like the Ara and Devine era's in the 60's and 70's. ND was national title contender for nearly all of those 6 years in that period winning it in 1988. They also won National Titles in 1966, 1973 and 1977.
