Duke was 15-5 and 6-3 on the road, including a loss to Princeton in NJ. Princeton is 13-4, which is a better record that Duke and while loses to Rutgers and Harvard do not help, they beat Duke. UConn is the defending champs and is 18-3, lost to the same teams as Duke (Princeton, Maryland, UNC) but also did equal of better than Duke with other mutual opponents (Liberty, Old Dominion, Syracuse). Thus, Princeton should be the 3 seed and UConn the 4 seed. But, clearly, wins and loses over other ACC opponents seem to matter more to the selection committee.
Would the following be fairer? It keeps the mileage down for the small school except for Miami OH, which is unavoidable, breaks-up the ACC, and puts the 4 seed (UConn) and the 5 seed (Duke) in the same pod.
