I think in the 2013 game we outgained the Chiefs something like 415-180. When Tuel threw that long touchdown to Marquise Goodwin early on it looked like it was going to be our day.
And beyond the 4th down Jamaal Charles run in 2014 and Bryce Brown's awful fumble, I still can't forget the Alex Smith designed keeper that pretty much iced the game. Had the Bills won that game they would've been 6-3. It was a huge factor in them missing the playoffs.
