Ryan became the defensive coordinator in 1993, and his defensive team helped propel the Oilers to an 11-game winning streak at the end of the 1993 NFL season. Then the Oilers were upset by the Kansas City Chiefs, led by Joe Montana, in a home game during the divisional round of the 1993 - 94 playoffs. On January 2, 1994, Ryan was involved in a sideline altercation with the Oilers' offensive coordinator Kevin Gilbride during the nationally-telecast game.
Ryan had been criticizing Gilbride's "run and shoot", referring to it as the "chuck and duck." Ryan thought that last-minute defensive stands lost him two players to injuries when the offense could have simply run the clock out. At the end of the first half in the last game of the regular season against the New York Jets, Gilbride called a pass play, and when Cody Carlson fumbled the snap, Ryan started yelling at Gilbride, who then started walking towards Ryan, yelling back. When they were at arm's length, "Ryan ... punched Gilbride in the jaw" before linebacker Keith McCants and several other Oilers players separated them.
Seems like a familiar theme
