Lost in the shuffle of Super Bowl week is Kyle Williams, whose two turnovers in the NFC Championship game may have cost the Niners a trip to the big game last year.

The most costly of the mishaps came in overtime, when he fumbled a punt deep in Niners’ territory, allowing the New York Giants to advance to the Super Bowl on a game-winning field goal.

Now, Williams is speaking out against the league for failing to punish the Giants, who admitted to targeting the wide receiver in the championship game.

“The thing is, we knew he had four concussions, so that was our biggest thing was to take him out of the game,” said the Giants’ Jacquian Williams after the game.

The NFL did not punish any of the Giants for specifically targeting Williams’ injury, and he is clearly unhappy with it.

“The league announced the bounties and that (former Saints defensive coordinator) Gregg Williams said the same things the Giants were saying,” he said, referring to the “Bountygate” scandal, where the Saints paid their players to injure their opponents. “They took it to the highest level they could with the Saints. But it seemed like the league decided it was no big deal what the Giants said.”

Williams suffered a season-ending injury against (ironically) the Saints in Week 11, tearing his ACL.
