When I was a kid in the 70's my dad was a Cheektowaga cop. He was on the detail that was tasked with escorting the visiting teams from the Sheraton on Walden to the stadium on game day and then from the stadium to the airport. For that, the two cops used were given tickets to the game and a few bucks (cash usually). My dad used to use the money they gave him to buy me a ticket to the game (about half the time the visiting teams would just comp him the ticket.) As a result, I got to the games well before anyone else, even before the Bills players typically arrived.
Sooooo, I we would hang out at the players entrance as they arrived and collect autographs. I have many of the greats of that era, including OJ, Fergie, Reggie MacKenzie, etc. I also met a number of opposing players of that era. The two that stand out are Ken Stabler and Joe Namath, both of whose autographs I have.
Namath was great! He rode in his own limo, and my dad asked him for an autograph for me (I was far too starstruck to say anything) he said "Sure" to my dad and looked down at me with a great big smile, and grabbed the Bills logo on my coat and said "Where did you get that jacket kid?" Then he took me into his limo and we sat and talked about football, school, and such. He gave me his autograph and sent me on my way. Classy guy!
