Erhardt compiled a 21-28 record in three seasons as head coach of the Patriots -- he served as co-head coach with Hank Bullough for the team's final game in 1978 before taking over the following year.
During Erhardt's eight seasons as offensive coordinator, the Giants reached the playoffs five times, won three NFC East titles and two Super Bowls. Phil Simms was the quarterback for the first one over Denver after the 1986 season, and Jeff Hostetler ran the team en route to the second title after Simms broke his left foot late in the 1990 season.
"I learned an awful lot from him. He went on and did some amazing things offensively," Hostetler said. "What amazes me, is that system is still out there, still being used, and works as successfully as ever. It is -- without a doubt, out of all the systems I've been involved with and that's probably five, six, or seven different systems -- the most simple as far as verbiage, and most consistent."
