[1] Grant went on to become a fixture on head coach Joe Gibbs' Redskins teams in the 1980s.

At times paired alongside other Redskins defensive line standouts such as Dave Butz, Dexter Manley and Charles Mann, Grant was one of the contributors during a period (his Redskins career 1981–1990) that saw the Redskins make the playoffs six times, including three trips to the Super Bowl (two wins) and four conference championship appearances (three wins).

Grant intercepted a pass and returned it for a ten-yard touchdown in the 1982 NFC Championship game against the Dallas Cowboys, which the Redskins eventually won 31–17.
