Kyle Williams is taking full responsibility for his punt-return fumble, which set up Lawrence Tynes' winning 31-yard field goal in overtime Sunday night, calling the moment "painful." New York won the NFC Championship Game over San Francisco, 20-17, earning a trip to the Super Bowl. "I really didn't pay attention to Twitter," said Williams, who was filling in for injured punt returner Ted Ginn Jr. "All the feedback I needed was family and friends, the guys in the locker room." Shortly after the game, Williams was made a villain on the Internet and he received a number of death threats. "It's one of those things you have to take accountability for," Williams said. "Everybody is responsible for what they do on the field. It's something that I was responsible for, and I made a mistake and it's time to own up to it and move forward."
