Williams says 'small, minor detail' tipped him off on Matthews INT

CHICAGO – Tramon Williams said it was a "small, minor detail" he saw during film study this week that tipped him off in the third quarter Sunday.

In the backfield, the Green Bay Packers cornerback saw Chicago Bears tailback Matt Forte shift before the snap. His first thought? Gotta be a pass.

"You shift a back over almost out of the box, he's not going to stay in and block," Williams said. "He's going to get out for a route. You know he's got to get the ball out quick, so I was anticipating it."

Williams scooted tight against Bears receiver Josh Morgan. He was close enough to jump quarterback Jay Cutler's pass. The football deflected off Williams, into the air.

When linebacker Clay Matthews settled under it – and returned the interception 40 yards – the Packers had their biggest play in a 38-17 win against the Bears at Soldier Field.

"Oh, man, I wish I would have had that myself, but I was glad to see a teammate there to make that play," Williams said. "It was big for us at that point. The way our offense was moving the ball, we wanted to get those guys the ball, and they didn't disappoint at all."

Until that point, the Packers defense hadn't found much success. Chicago's three, full drives in the first half ended in points. The Bears ran out of time on the goal line during their fourth drive, which ended the opening half.

Matthews' interception came on the Bears opening drive of the second half. The play seemed to turn momentum. Chicago never scored in the second half. It finished with two second-half turnovers, both on Cutler interceptions.

"It was big," Williams said. "The way the game was unfolding, they couldn't stop our offense and our defense stopped their offense. We know what we're capable of on the back end, and we know we're capable of turnovers on this defense. We didn't come in here thinking we were going to rely on it, but it's always in the back of your head.

"That's the No. 1 stat out there – turnover ratio. That's how you win, and we made the plays necessary to win the game."
