There were ghosts in the Superdome. It’s obvious, in retrospect, but there were definitely spirits lingering in the rafters of the huge stadium, some benevolent and some less so, but all alike watching the Final Four with rapt interest. There may have been an echo of the 20-point loss to Duke in Chapel Hill in the regular season, toying with fans’ expectations. There was definitely the rodential specter of the Coach K farewell tour gnawing at the already-frayed nerves of Tar Heels everywhere in the week preceding the Final Four. These ill omens hung heavy around that court in the middle of the sea of humanity, congregating around the bright spot of hardwood flooring amongst the sea of black plastic seats.
