Khalil Delshon Mack is an American football Outside linebacker for the Chicago Bears of the National Football League (NFL).
In 2015, he became the first player in NFL history to be selected first-team All-Pro at two different positions, defensive end and outside linebacker, in the same season.
Leading up to the 2014 NFL Draft, Mack was projected as a high first round pick in many mock drafts.
He was selected with the fifth overall pick by the Oakland Raiders, making him the highest selected Buffalo player ever, and the first (and only) selected in the first round.
Previously, the highest selected player from Buffalo was defensive tackle Gerry Philbin, who was selected with the 33rd overall pick by the New York Jets in 1964.
