As December rolls on, heavyweight nonconference matchups that are beginning to carry real resumé weight, showcase games in neutral-site arenas and hostile road environments are now offering teams little margin for error, and this past week delivered several moments that will echo well into March. The Jimmy V Classic in New York provided one of the season’s early classics, highlighted by BYU’s stunning 22-point comeback to beat Clemson at the buzzer and UConn’s revenge win over Florida after last year’s tournament heartbreak. Elsewhere, Arizona and Michigan continued their steady dominance, with the Wildcats making a loud statement by dismantling Alabama in Birmingham. Nebraska kept its perfect start alive in dramatic fashion by stunning Illinois at the horn in Champaign, further tightening the race among the nation’s unbeatens. Duke took a brief pause from game action, but the spotlight quickly returns with a looming clash against Texas Tech in New York.
