Bob Kratch.
This is one of those numbers where I really was hoping to find an old-timer who deserved it. No luck, though.
Kratch was a decent offensive lineman who played for the Giants from 1989-93 before moving on to the New England Patriots. He became a starter during his rookie season.
Chris Godfrey was a Giant lineman from 1984-87, starting at right guard much of that time.
Charlie Harper was a backup offensive lineman for seven seasons, 1966-72. The Adam Koets of his day -- it looks like he never played.
