"For more than a decade, Favre has been a joy to watch and a darling of the football gods. But now his powers are declining, and when great athletes begin to lose abilities they once had, many find this hard to face. For the great athlete, everything in life has been an upward arc -- through youth, college, the pros and finally national renown, things just keep getting better. Then suddenly things stop getting better and performance begins to decline. In Kelly's final season, he threw a bad interception at the goal line in a close loss and came off the field repeating aloud over and over, 'I don't understand it.' The phrase 'I don't understand it' must run through the heads of many stellar athletes as their abilities deteriorate and the curtain call approaches. This thought must be running through Favre's head now."
What game is he referring to?
