In January 1987, Martin was one of the team captains for the Super Bowl XXI champions; late in the second quarter, Martin sacked Denver QB John Elway in the end zone for a safety, cutting the Broncos' lead to 10-9 where it held until halftime.
In November 1985, Martin became the NFL's all-time leader in touchdowns scored by a defensive lineman (DL), with 5, when he returned an interception for 56 yards against the St. Louis Cardinals.
In the following championship season, Martin became the league's career leader in TDs scored by a DL as a DL (at 6) when he returned an interception for 78 yards and 6 points in an late season home game against the same Broncos team they defeated in the Super Bowl, a feat which Giant head coach Bill Parcells has called the "greatest football play I've ever seen.
In addition, Martin amassed over 90 quarterback sacks in his Giants career (his official NFL total is 46 [the NFL did not begin counting sacks officially until 1982]; the Giants credit him with 96),[2] during which time he was generally regarded as one of the league's most feared pass rushers.
