I would add a few guys who may or may not have met your criteria but certainly deserve consideration:
Don Perkins - Perkins retired as the #6 all-time rusher and was an all-pro/pro-bowl selection several times while playing on some lousy teams.
Jeff van Note - van Note was one of the best Centers in the league for many years but again played for some lousy teams so he was overlooked.
I've got to run but I thought I would throw those two names out now and add some more later when I have time to do a little more research.
Great list though.
Captain Nathan Brittles: "Only the man who commands can be blamed. It rests on me... mission failure!"
"Jerry Jones is a billionaire fan who bought his own team for the express purpose of buying his way into the game. He wants to hang out with the players, stand in front of the cameras, be the face of the team (yech), make personnel moves as if this were a video game, and more than anything else, be seen as the guy who made it all happen."
