John Hannah (1991)
Hannah, a guard, played his entire career for the Patriots (1973-1985). Sports Illustrated famously crowed over Hannah's blocking ability in 1981, calling him the best lineman of all time. A nine-time pro bowler, Hannah was named offensive lineman of the year for four straight years (1978-1982) -- spanning the first four years of the award's inception. He was inducted into the Pro Football Hall of Fame in 1991 and became a member of the Patriots Hall of Fame the same year.
