In the semi-final game against Denny Crum's Louisville team, Lester scored the first 10 points for Iowa. But after eight minutes of play he reinjured his knee and exited the game, ending his Iowa career. In Lester's absence, Louisville bested Iowa by only eight points, 80–72 and went on to win the Tournament, defeating UCLA, led by Larry Brown, in the final. Lester's value to his team was evident in the numbers. Not counting the Louisville game, they were 15–1 with Lester and 8–9 without him. Hall of Famer Earvin "Magic" Johnson, who played two seasons at Michigan State, once claimed Lester the toughest opponent he ever faced in the Big Ten. Lester was drafted 10th overall in the 1980 NBA Draft, but the knee issues limited him in the NBA. He donated $100,000 to the University of Iowa in 2009.
