Duke was missing senior Ryan Kelly (see last year's ACC Tournament and Lehigh game for his importance), but there was simply no leadership from the seniors. At least Jefferson and Murphy showed their potential. Hairston and Thornton are nice to have in 8-10 minutes off the bench, but are ACC starters and should not be playing major minutes.
But the real disappointment was the lack of leadership from the other seniors (Plumlee2 and Curry). The shots were not falling (though Mason redeemed himself somewhat in the second half), but there was no effort on defense and no leadership displayed (and both players are captains).
That being said, I will be heading to Durham for the Duke-Miami game in March. Going back to my days at Duke Law School, I am 28-0 when I see Duke play in person (this includes three Duke-UNC games, with one of them being played at the Dean Dome).
