I was referring to Sanders but was thinking of a pass to Kittle and Bourne that were short. But two things: 1 all they needed was a first down and the game was over so the fact it was a deep pass is irrelevant and 2 Sanders was wide open and Jimmy sailed the ball on a throw he needs to make. Lastly, and really more to the point, they run the damn ball three times and KC has little tone and no timeouts for a last drive.
Long story short, the Niners had the lead inside of two minutes needing a first down to win. I'd say that is as close as the others.
