The Tribe (22-9) advances to Monday's 7 p.m. championship game against top-seeded Old Dominion (25-8), while the Huskies drop to 20-12 with the loss. It will be W&M's second trip to the title game in the past three years, and it will be looking to win its first CAA championship and earn a berth in the NCAA Tournament for the first time.
Senior guard Danny Sumner (Fairfax, Va.) tallied a team-high eight points for the Tribe, while junior forward Marcus Kitts (Holly Springs, N.C.) contributed seven points and a team-high nine rebounds.
Northeastern was led by senior forward Manny Adako (Decatur, Ga.), who scored a game-high 14 points, and senior guard Matt Janning (Watertown, Minn.), who chipped in 12 points.
Northeastern jumped out to an early 4-0 lead, but a pair of long-range jumpers by senior guard Sean McCurdy (Jersey City, N.J.) and Sumner sparked a 16-2 Tribe run to give W&M a 16-6 advantage with 9:14 left in the first half. The Tribe increased the advantage to as many as 16 points before taking a 31-17 lead into the locker room.
Northeastern turned the tables in the second half, opening the period on a 16-6 run. Janning's jumper with 11:07 remaining trimmed the lead to four, at 37-33. The Huskies held the Tribe without a field goal for over nine minutes until Matt Rum slashed to the hoop and was fouled on the made basket.
The Huskies tied the game at 39 on a pair of free throws by senior guard Baptiste Bataille (Ferin, France) with 5:37 remaining and NU took the lead for the first time since 4-3 when Janning was fouled and hit both from the charity stripe with just over three minutes left.
Down 43-42, Sumner's jumper bounced off the iron, but Kitts tipped it in to give W&M a one-point lead with 1:30 left. Adako answered, giving the Huskies the lead back, 45-44, on a jumper with 1:01 to go.
On the ensuing possession, sophomore guard Quinn McDowell (Mason, Ohio) found Schneider on the right wing for the game-winning 20-footer with 37 seconds left. Schneider, who is the Tribe's leading scorer and the all-time 3-pointer leader in school history, had been 0-for-8 from the floor and 0-for-7 from beyond the arc until that point.
Northeastern had seven shots in the final 20 seconds to tie or win the game. Senior Nkem Ojougboh's (Scottsdale, Ariz.) layup in the closing seconds rolled off the rim to give the Tribe the victory.
The Tribe improved to 10-4 this season in games decided by three points or less, which includes a 53-52 triumph over Northeastern during the regular season.
W&M shot just 26.1% from the floor in the second half and 37% for the game, while NU shot 34% from the floor, including only 24% in the first 20 minutes.
