The AP story on the Kentucky game leads with the fact that this is the first 7-0 start under Roy Williams, and the team's best since the '98-99 season. My curiousity piqued, I went looking for UNC's best starts in the ACC era:
Season Streak 56-57 32 wins 83-84 21 wins 85-86 21 wins 97-98 17 wins 81-82 13 wins 66-67 9 wins 94-95 9 wins 92-93 8 wins 84-85 8 wins 98-99 8 wins
There are another three seasons that started out 7-0 - '55-56, '68-69, and '73-74. It'll be interesting to see where this year's squad ends up on this list.
