Man, I used to love to watch those guys play the game!  Often wondered about them after retirement.  Hope they are alive and doing well.
Never seen them interviewed since retirement that I can recall.

Still see Bergey in commercials for his tire place every now and then. Guess he's still alive.

Conrad Dobler was the only guy Lee Roy Jordan (Dallas Cowboys) ever openly complained about playing dirty.
Claimed Dobler bit him on the leg in a pile-up.  Had the bite marks to prove it too.

My friend and I were standing outside the stadium in Milwaukee after a Packers - Saints game.  The Saints had just suffered their first loss of the season.  The Saints players started coming out to get on the team buses and my friend spotted Conrad Dobler.  He stepped to him and asked, "Hey Conrad, are you really the dirtiest player in the NFL?"  Dobler snarled back at him, "You're goddamn right I am!"
