Marino is pretty much a given. He WAS the Miami Dolphins for 17 years.
O.J. McDuffie was my favorite. A total class act. Gave it his all on the field and was a nice guy off the field. He's always come over and sign after shagging punts and being the last person off the practice field.
As a kid I really admired John Offerdahl. He was an animal. His career was cut short only because he was all out on every play. He had great instincts.
