Ex San Diego Charger coach Don Coryell passed away from unknown causes at age 85. The offense known as "Air Coryell" was a precursor to a lot of the offenses ran today. Coryell is known as a pioneer of the aerial attacks that he ran in the 70s and 80s with the San Diego Chargers. Back then they were one of the most exciting teams to play the game.They never won the Super Bowl or even went to one,but you can't deny the long range impact that Coryell and the Chargers had on the game. He was definitely an innovator of the game. Hopefully he will get his due by getting enshrined in the Hall of Fame.
