First impressions aren’t everything when it comes to Harvard sharpshooter Laurent Rivard. If they were, then Rivard might not be thought of as maybe the greatest shooter in the history of the men’s basketball program. Rivard arrived on campus as a freshman recruited to shoot the ball, and shoot it well. But he came out of the first game of his Crimson career with the same amount of makes as when he walked onto the floor. He went 0-for-11 from the field against George Mason, including 0-for-7 from behind the 3-point line. That game remains etched in his brain. “I mean 0-for-11 is pretty hard to forget,” Rivard said. “(The coaches) always wanted me to keep shooting because they believed the next one is going in, and I’ve learned to believe that with them.” The coaches were right. Rivard has made 282 shots from behind the arc since that 0-fer in his debut, which ranks him No. 1 all-time at Harvard and second in Ivy League history. He is shooting a career-best 42.6 percent from behind the line this season while averaging 10 points per game. “It’s a testament to how unselfish this team is,” Rivard said. Dive a little deeper into Rivard’s numbers and it proves why coach Tommy Amaker goes to his senior with a game on the line. Rivard delivered to beat Yale in the final moments last Friday with a 3 from the corner to clinch the Ivy title outright for the Crimson, and he did so again Saturday with 37 seconds left to close out the regular season with an overtime victory over Brown. As Ivy League champions, Rivard and Harvard will make their third consecutive NCAA tournament appearance. Rivard is shooting nearly 57 percent from the field in the final five minutes of games this season, and he is at 52 percent (13-for-25) on 3’s. From the free throw line, he is hitting 85.2 percent in crunch time. Amaker said Rivard is really the only guy on the team who has the constant “green light.” The numbers show why. “He’s always been a guy who loves big moments and to take big shots,” Amaker said. “He’s done that throughout his career.”
