Duke finishes the year 22-10 / 8-9 in the conference after their first round conference tournament loss to NC State.
So does Duke deserve an invite to the field of 64?
If they do, then you've got a whale of an argument on your hands because as far as I can tell, there isn't much difference between Duke, Georgia Tech, Clemson and Florida State.
The top 5 teams in the ACC (UNC, Virginia, Virginia Tech, Maryland and Boston College) get in because they each have at least 10 conference wins. Both Georgia Tech and FSU have more wins (3 each) against top 25 teams (Duke has 1), as well as fewer losses to top 25 teams (4 each, compared to 5 for Duke). If you take Duke, you also have to take GT and FSU and give the ACC 8 bids.
As an ACC fan, I can tell you that the league certainly doesn't deserve 1/8th of the total bids.
Coach K and his boys better hope a whole lot of bubble teams lose early in their conference tournaments...
