Ours came with NFL teams: the Bears and the Chiefs (although the kicker didn't kick like Jan Stenerud). My older brother special-ordered the 49ers from the sheet inside the game box.
The Bears had one running back who ran completely straight. You put him in the backfield, thirty yards behind the line of scrimmage, and by the time he reached the line everyone had veered to the sideline. There was some player combination that, if they hit each other at exactly the right angle, would dance around in a square dance for the rest of the play.
