Add Joe Namath, Johny Unitas, and other players to madden 20 or 21

Appreciate the submission! No official word over here on whether they plan to be added in the near future, but they surely are some of the greats that many players would love to see in the game. If Joe makes it in the game, I'd hope the finger pointing to the sky is added in there after touchdowns or post games. 

If there's any other players you want to see added to the game, let us know. We'll do our best to pass up the feedback for you all.
