Sad to hear this, I'm an original 1960 era Bills fan, Marty played for the Bills 1965-1968.
Had a reputation as a ferocious tackler, was the fourth linebacker on a great 1965 Bills team/defense that I always wished had gotten a shot at the Pack, who had trouble scoring against a mediocre Cleveland Defense in the NFL Championship.
Two teams were very evenly matched, and both had great depth.
Wonder if his hard hitting in any way led to this latest challenge.
In that 1965 Championship Game, the Bills, east coast team traveling to the Left Coast, hung a donut on the top seeded Chargers.
