Best Comebacks
[Tournament games only] March 9: #115 George Mason 82, #197 Fordham 71 (OT) (0.6%) The Patriots were down by seven with 47 seconds left and it was Fordham’s ball. A timeout was called. In the huddle Mason head coach Dave Paulsen said some motivational words.
Something like, ‘We are going to win this game and extend our season. What do you think?’ And his players were like, ‘Yeah, yeah, yeah, let’s do it.’ GMU clawed back into it and Marquise Moore was at the line for two free throws with seven seconds left and if he made them both, the game would be tied. Moore missed the first free throw and he missed the second as well. But Justin Kier remembered the inspirational words of his coach, and got the offensive rebound and Jalen Jenkins would make a game-tying bucket to force overtime, where Mason would win easily. It’s also worth noting that Moore had 19 rebounds in this game. He’s 6-2. He finished 11th nationally in defensive rebounding percentage.
