The Chicago Bears hired renowned martial arts expert Joe Kim to be a skill development coach for the 2014 season, a league source confirmed Tuesday evening.
Kim will work with all of the Bears' position groups on enhancing their use of hands when blocking or escaping blocks, per the source.
Kim was hired as a pass-rush consultant by the Kansas City Chiefs from 2010-12, according to the official website of Kim's Martial Arts School. Current Bears general manager Phil Emery was the Chiefs' director of college scouting from 2009-11.
In addition to Kansas City, Kim has consulted for the Cleveland Browns, Miami Dolphins, New York Giants, Buffalo Bills, Dallas Cowboys, Denver Broncos, Green Bay Packers and Penn State. Kim was also the Browns' assistant strength coach from 1992-95 and 1999-2000.
Kim's website calls him "one of the most successful Taekwondo Instructors and Coaches in the United States."
The Bears had just 31 team sacks in 2013, down from 41 team sacks the year before in Lovie Smith's final season in Chicago.
