In short: It was the start of the Chiefs downfall.
It was week nine of the 2007 NFL season and the Chiefs had beaten the Oakland Raiders in the previous game with an ugly score of 12-10. We knew the Chiefs weren't very good but they were still 4-3 and clinging for life.
There was no indication what was going to happen next.
The Chiefs got up 22-16 in the fourth quarter and were looking to secure the victory.
Boom. Larry Johnson is pulled down
by his hair (Edit: I was thinking of LJ pulling Troy Polamalu down) and suffers a season-ending foot injury. Boom. The Packers score 17 unanswered to win the game.
Boom. The Chiefs lost nine straight to end the 2007 season.
The Chiefs would go on to lose 19 of their next 20 games and 28 of their next 30.
Those 30 games (and really the rest of the 2009 season) were the lowest of the lows in the history of the Kansas City Chiefs.
We'll see if this time around a Chiefs victory is the start of a long streak of victories.
