Martin played 201 regular season games for the Giants between 1975 and 1988. He was a member of the 1986 Super Bowl championship team (coached by Parcells) and recorded a safety of John Elway in SB XXI. Martin was enshrined in the Giants' Ring of Honor in 2010.
Here's an additional tribute from Bill Belichick:
"Bill Parcells has been thought of as one of the all-time greats for a long time, so it is with great pride that we can officially refer to him as a Hall of Famer. He deserves all the recognition he is getting and for his career to be celebrated in Canton forever."
