I was looking at past seasons to see how well the conference has done over the years. The ACC actually had a few really good season sprinkled in the last 20 years. I remember during the 90s the ACC still got little respect, but reflecting back I think alot of it had to do with there were always 3-4 teams in any given year that were non-competitive while most other conferences usually had 1 or 2 and a few more members.
2000 looks like one of those years where the conference from top to bottom had a good season:
#3 FSU 11-2, wins vs #8 UF and #37 Louisville
#13 Clemson 9-3, win vs #33 USCe
#15 GT 9-3. win vs #24 UGA
#43 NCSU 8-4, win vs #56 Minnesota
#44 UVA 6-6
#46 UNC 6-5, win vs #39 Pitt
#64 UMd 5-6
#102 Wake 2-9
#104 Duke 0-11
