The Pittsburgh Steelers are not unique in this respect, but they certainly have one of the most well-attended groups of alumni in the National Football League. Moreso than most organizations, they make an active and conscious effort to keep their former players in the loop and a part of their proceedings. Hell, they even have a couple of former players on their staff.
Some things don’t always end as they would hope, however, as we have perhaps mostly recently seen with the departure of Troy Polamalu, who has so far declined to participate in event since he basically was asked to retire.
