It was a game of historic proportions. And the Memphis Grizzlies were on the right side. As the final buzzer sounded at FedExForum, fans stood and cheered as the Grizzlies won by the largest margin in NBA history, 152-79 on Thursday night. The 73-point win surpassed a 68-point victory by the Cleveland Cavaliers over the Miami Heat on Dec. 17, 1991. The Grizzlies also broke the franchise record for most points in a game. The Grizzlies didn’t waste time pouncing early and then poured it in record fashion. When John Konchar flew in for a thunderous dunk over Isaiah Roby in the fourth quarter, the Grizzlies surpassed their previous franchise record of 144 points.
