John Teerlinck (born 1951) is a former Americanfootball player. He now is a defensive linemencoach for the Indianapolis Colts. While in college he studied Fred Dryer and employed those moves in hi play, "We used to get New York Giants games at Western and I`d watch No. 89, Fred Dryer, and copy his moves", Teerlinck said. 
Teerlinck came under fire in 1996 amid allegations that he taught his players to aim for opposing quarterbacks' knees; the allegations were substantial enough that then-NFL commissioner Paul Tagliabue summoned him to a meeting for a warning.
