If you don't know the answer - you definately should learn about this player. He was a stud on defense on a team of studs. During a 3 year period in the regular season they won 36 games with only 4 losses and a few ties. They set sack records which while not an official stat back then - were damn impressive and I beleve their single season sack yardage is still the record.
Like Willie Brown he played for the team in Denver that wears Orange before coming to the Raiders. An all time great Raider that deserves some love IMHO.
