Question: Did the coach of the Chargers from 1992 to 1996 coach any other professional teams? Passage:Bobby Ross coached the Chargers from 1992 to 1996, and is the only coach to win awards while coaching the Chargers. In 1992, Ross won the Pro Football Weekly NFL Coach of the Year, the Maxwell Football Club NFL Coach of the Year and the UPI NFL Coach of the Year. The Pro Football Weekly NFL Coach of the Year is presented annually by various news and sports organizations to the National Football League (NFL) head coach who has done the most outstanding job of working with the talent he has at his disposal. The Maxwell Football Club NFL Coach of the Year was created in 1989 and is originally titled the Earle "Greasy" Neale Award for Professional Coach of the Year. The United Press International (UPI) NFL Coach of the Year award was first presented in 1955. Before the AFL-NFL merger, an award was also given to the most outstanding coach from the AFL. When the leagues merged in 1970, separate awards were given to the best coaches from the AFC and NFC conferences. The UPI discontinued the awards after 1996.
