The Niners had just stopped Eli Manning, forced a Giants punt, and racked up their sixth sack on the day. And then Kyle Williams made his second error on a punt return of the 2012 NFC Championship Game. This one may be fatal to the Niners' Super Bowl XLVI chances.
Kyle Williams had the ball punched out by Jacquian Williams of the Giants, who had already made a couple of plays on defense.
None will be bigger than his brilliance on special teams, especially if New York can convert their fantastic field position to a scoring drive that propels them to the Super Bowl.
