HOUSTON — It was a game played under the specter of history: Each side is proud but on different scales. On the one was Villanova, a program whose history has been defined by an unlikely championship three decades ago and which has since been dedicated to the chase of an elusive second one. On the other was North Carolina, owner of five titles and forever expectant that the next one might come now. Reminders of each laced NRG Stadium. In the stands were a number of Villanova fans clad in T-shirts reading PARTY LIKE IT’S 1985, as was Rollie Massimino himself, the coach of that team, who sat behind the Wildcats’ bench.
