Buffalo's kicker had a 78 overall rating, if it matters.
I lined up the kick perfectly in both situations (even the meter at the bottom of the screen was accurate for the split second it was "un-iced") but still missed both kicks. I wonder if icing a kicker does more this year on higher difficulty levels than it did in the past, because in past years, even when iced I was still usually able to make short kicks with ease.
