The other factoid of useless trivia associated with the QB greats of that era (I will also include Montana even though he was already in the league before '83) that I find interesting as I'm from there originally, is that most of them came up in the steel mill geography of western PA--nicknamed the Cradle of Quarterbacks because it literally churned out so many good ones--Marino, Kelly, Montana, Hostetler, and before that, Unitas, Namath, just to name a few...good article about that here:
