Ron Erhardt, a former head coach of the Patriots and offensive coordinator for two Super Bowl-winning Giants teams, passed away on Wednesday morning. He was 80 years old.

Erhardt was the head coach of the Patriots from 1979-81, compiling a 21-28 record in that time span. He then joined the Giants as the offensive coordinator on Bill Parcells' staff and was with New York until 1991. During that 10-year time span, the Giants made the playoffs five times and won two Super Bowls, one with Phil Simms under center, the other with Jeff Hostetler under center.

"Ron was a wonderful man and a great coach," Giants CEO John Mara said in a statement. "He was a big part of our success in the 1980s and was an important contributor to our first two Super Bowl championships."

Erhardt also served as the offensive coordinator for the Steelers (1992-95) and Jets (1996-97) before retiring from the NFL.

"I enjoyed Ron and his personality," said current Giants head coach Tom Coughlin, a former co-worker with Erhardt under Parcells, along with Bill Belichick. "Ron had a lot of fun — let's put it that way. He was a (kidder). He enjoyed it, and everyone enjoyed it with him. He had one of those cantankerous laughs. I remember, in the offseason, the coaches would be running and lifting before the start of the offseason program. Ron would be hitting golf balls into a net down in the stadium. He wasn't about to do any of that running and lifting stuff."
