I have to say, the interception on the end zone was a poor pass by the KSU QB, high and a bit behind the receiver. Those kind of passes tend to get tipped up and since there are more defensive players back there than offensive players, the odds are good for the defenders. Throw that pass low and in front of the receive and it is incomplete or a TD.
I give the Barn DB credit for being in the right place and maintaining focus on the ball. (The KSU receiver was well into his "Darn, I didn't catch the pass" motion when the Barn DB was catching the ball.)
Three missed FGs is not really luck, as bad mechanics by the kicker (plus, maybe a little luck with the wind, which I guess was blowing pretty hard Thursday in the Little Apple). Still, two of those three FG attempts were chip shots that the wind had little opportunity to influence, and if they had been made, the game might have gone into overtime. Physics.
