If we can finish ninth in 2011 and get a three seed, Duke can finish fifth this year and get a two.
The problem I have is that you can't overlook Duke finishing fifth and then reward UNC for winning the regular season title, especially in a conference where the schedules are so imbalanced. Their resume becomes suspect under further scrutiny - only one of their top 50 wins came on the road (@ #40 Wake) and all five of their top 25 wins came at home. They lost on a neutral court to two teams seeded below them and they lost two games to teams that did not make the tournament.
Duke winning @ Notre Dame and @ Virginia carries more weight to me, in addition to their wins over Florida, Louisville, UNC, Rhode Island, and Notre Dame on neutral courts. That, in addition to their injuries, makes them a one seed in my opinion.
