National championship game
In the Division II National Championship Game, top seeded Findlay Oilers played third-seeded Cal Poly Pomona Broncos. The Broncos, who had traveled 10,000 miles over the postseason, were losing to the undefeated Oilers for much of the game. Cal Poly Pomona managed to tie it at 18–18 before the Oilers went on a 12–2 run to lead by 10 at the half. Findlay widened the lead to 14 with slightly over 16 minutes left. That was the last time the Oilers scored for the next eight minutes while the Broncos recorded 13 straight points to come within one.

Walter Thompson, the point guard for the Broncos, made a three-pointer with 7:08 in regulation to tie the game at 38. They snatched the lead on the next possession at 41–40. Cal Poly Pomona center Tobias Jahn added a point on his two free throws for a 42–42 tie. With 1:42 left in the game, neither team managed to put points on the board. After Thompson missed a rebound on Austin Swift's attempted 3-pointer, the game went into overtime.

Throughout overtime, the lead changed several times. The game was tied at 53 with 24 seconds left on the clock. The Broncos' defense forced a held ball on Findlay with 2.4 seconds remaining, with possession to Findlay. On the inbounds play, Tyler Evans hit a three-pointer at the buzzer—his only three of the game—sealing the Oilers' victory by a score of 56–53.
