Story of the game
Both defenses were locked in early as the score was just 2-2 after a little over five minutes. After a three-pointer by Jabari Rice, Connecticut went on a 12-3 run to go in front 12-8.
Allen then began to heat up as he score seven of New Mexico State's next eight points to give the Aggies a 15-14 lead. He scored or assisted on nine of the WAC champion's final 11 points of the half.
His assist on a triple by Johnny McCants as the shot clock expired gave New Mexico State a 30-20 advantage, their largest lead of the game to that point. The Aggies led 32-22 at the half.
Clayton Henry nailed a straightaway three 1:38 into the second half to stretch the lead to 38-24. A 14-4 run by Connecticut cut the Aggies' lead 42-38 with 12:28 remaining.
The teams went back and forth and Tyrese Martin's free throws with 5:08 left knotted the score at 52-52. A huge three by Henry put New Mexico State back in front, but the Huskies would tie things up on a layup by Isaiah Whaley.
Allen took over at that point. He broke the tie for good by connecting on a three with 1:43 left. Two more free throw makes from Allen with 52 seconds to go answered a driving layup by R.J. Cole.
His drive through traffic after forcing the Huskies' eighth turnover of the game that iced it. He twisted his way inside, hit a layup, got fouled and calmly nailed a free throw to complete his three-point play which pushed New Mexico State's lead to 66-60 with 27 seconds left.
Martin brought Connecticut a bit closer with a three with 18 seconds to play, but Allen sealed the game, hitting four free throws to send the Aggies into the second round.
