ARLINGTON, Texas » The Steelers had all the momentum. The Terrible Towels were out in full force around Cowboys Stadium. Rashard Mendenhall took the handoff with every intention of moving Pittsburgh a little closer to completing an improbable comeback.

Then, a big hit, the ball popped out of Mendenhall’s hands, and Desmond Bishop took off with it for the Green Bay Packers.

It would be the biggest mistake on a night filled with them for the Steelers. Green Bay hoisted the Vince Lombardi Trophy with a 31-25 victory yesterday.

"If you win the turnover battle," Bishop said, "there’s a direct correlation to winning."

The Packers won that category going away.

Therefore, they won the game.

Pittsburgh turned it over three times, and all three miscues were followed by Green Bay touchdowns. The Packers didn’t give it up once, allowing them to prevail when they were outgained (387-338 in total yards), had the ball nearly 7 minutes less than the Steelers and barely mustered a running game (50 yards on just 13 carries).

"When you turn the ball over like we did," Mendenhall said, "you put yourself in a bad position."

His fumble on the first play of the fourth quarter helped the Packers hold on, just when Pittsburgh seemed on the verge of overcoming an early 21-3 deficit.

Of course, let’s not forget Ben Roethlisberger throwing two interceptions, including a pick that was returned 37 yards for a touchdown by Nick Collins to give Green Bay a 14-0 lead less than 12 minutes into the game. The Packers stretched it to 21-3 — scoring again after Big Ben’s second interception — before the Steelers made a game of it.

"There’s a lot of what ifs. There’s a lot of throws I’d like to have back," Roethlisberger said. "We turned the ball over. A lot of that is my fault."

The fateful play came with Pittsburgh trailing 21-17 with a second and 2 at the Green Bay 33 as the final quarter started.

Mendenhall took the handoff, but Clay Matthews drove a shoulder right into the runner almost as soon as he got the ball, and massive Ryan Pickett dived in to complete a 595-pound sandwiching. The result of that fearsome collision: the ball came flying out, and Bishop swooped in to scoop it up.

"I just got hit and the ball came out. It just happened, and it should not have happened," Mendenhall said. "It’s tough. We did it to ourselves."
