Mississippi State called a timeout, and in its huddle Coach Vic Schaefer looked at William and said, “Mo, you’re about to win the game.”br William averages only about 11 points per game, but she had awakened her scoring in the N. C.A.br We didn’t have the kind of maturity that you need to win at this level at this time of the year.”br Williams, the swooping post player, kept UConn in the game with 21 points, 8 rebounds, 4 blocks and 2 steals,br but the Huskies’ offense was insufficient on a rare night of poor shooting.br We had to prove that we’re a way better team than we were last year.”br The Huskies (36-1) entered the taut, thrilling game — one full of runsbr and lead changes and gripping suspense — with a perfect record but were not a perfect team.br A championship that seemed inevitable for UConn ended instead with the stunningly improbable — a 66-64 defeat on a last-second shot in overtimebr and the startling extinguishing of a 111-game winning streak and a run of four consecutive national championships.br “When you get to this point in the season and you lose,” Auriemma said, “it’s the worst feeling imaginable.”br A version of this article appears in print on April 1, 2017, on Page D1 of the Newbr York edition with the headline: At the Last Second, UConn’s Aura Is Pierced.br With 26.6 seconds left in overtime, UConn had tied the game at 64-64 on a pair of free throws by Katie Loubr Samuelson after a flagrant foul for elbowing was called on Mississippi State’s Dominique Dillingham.
