Khalil Delshon Mack (born February 22, 1991) is an American football outside linebacker for the Chicago Bears of the National Football League (NFL). He played college football at Buffalo, and was drafted by the Oakland Raiders fifth overall in the 2014 NFL Draft. Mack holds the all-time NCAA record for forced fumbles and is also tied for career tackles for loss in the NCAA. In 2015, he became the second first-team All-Pro in NFL history to be selected by the Associated Press for two positions in the same year, as a defensive end and outside linebacker. In 1983, Lawrence Taylor was the first first-team All-Pro selection at two positions as an outside linebacker and inside linebacker. In September 2018, Mack was traded to the Bears for two first round draft picks and signed a six-year, $141 million extension, becoming the highest paid defensive player in NFL history. Mack is widely recognized as one of the most dominant defensive players currently playing in the NFL.
