So who were all of the characters supposed to be?

It goes without saying that Nick Nolte's character was based on the real life Peter Gent, that Mac Davis' QB character Seth Maxwell was Don Meredith, and Tom Landry was the inspiration for B.A. Strother. I've also heard it stated, though I can't remember where, that Delma Huddle the young black WR adverse to taking pain killers is supposed to be "Bullet" Bob Hayes. My father when he saw the movie told me he thought the two brothers who own the team in the film were a dead ringer for the Murchison brothers who owned the Dallas Cowboys at that time.

But what about the other main characters such as the Bo Svenson's character Joe Bob, John Matuszak as O.W. Shaddock, or Charles Durning as Coach Johnson? I had always assumed that the religious backup QB in the film was supposed to be Roger Staubach but an ESPN article I ran across claimed that Gent told the Washington Post after the film came out that it wasn't any one particular player but rather a composite character.
