On December 3, 1956, Chamberlain made his varsity debut as a center. In his first game, he scored 52 points and grabbed 31 rebounds, breaking both all-time Kansas records in an 87–69 win against Northwestern, who had Chamberlain's future NBA teammate Joe Ruklick. Teammate Monte Johnson testified to his athleticism: "Wilt ... had unbelievable endurance and speed ... and was never tired. When he dunked, he was so fast that a lot of players got their fingers jammed Chamberlain's hand and the rim." Reportedly, Chamberlain also broke Johnny Kerr's toe with a slam dunk. By this time, he had developed several offensive weapons that became his trademarks: his finger roll, his fade-away jump shot, which he could also hit as a bank shot, his passing and his shot-blocking. Leading a talented squad of starters, including Maurice King, Gene Elstun, John Parker, Ron Lonesky and Lew Johnson, the Jayhawks went 13–1 until they lost a game 56–54 versus Oklahoma State, who held the ball the last three and a half minutes without any intention of scoring a basket, which was still possible in the days before the shot clock (introduced 1984 in the NCAA). As he did at Overbrook, Chamberlain again showcased his diverse athletic talent. He ran the 100-yard dash in 10.9 seconds, shot-putted 56 feet, triple jumped more than 50 feet, and won the high jump in the Big Eight track and field championships three straight years.
