As a Green Bay fan, it pains me to post something about a loss, but this is too weird to pass up:
On December 15,  the week after the NFL season ended, the Green Bay Packers, undefeated NFL champions, came to town for what they expected to be an easy exhibition game. After all, opponents had scored only three touchdowns against the Packers all season. But Saunders and Maxwell had been negotiating a surprise. When the NFL season ended, Saunders paid two league players to come to Memphis. One of them was Joe Kopcha from the Chicago Bears. 8000 fans jammed the stadium and the sidelines.
