Three days after having time to review the play on film and stew on the consequences of his fumble, which was followed by the Bears' game-winning touchdown on the next play, Peterson was taking full responsibility.
With nine minutes left in overtime, Peterson took a short pass up the right sideline. After gaining 16 yards, linebacker Hunter Hillenmeyer punched the ball out and Nick Roach recovered. On the next play, Bears QB Jay Cutler hit Devin Aromashodu for the game-winning 39-yard touchdown.
"It was a great play by him, but as I was going down, I let the ball get away from my body and it gave him the opportunity to stick his hand, his arm in there and punch at it a couple times," Peterson said of Hillenmeyer. "That's pretty much what it was. As I was going down, I let my arm get away from my body and he made a great play."
After the game, Peterson said he would be motivated by the fumble. Peterson is already highly competitive, but he clarified that comment by saying he would concentrate more on proper technique to avoid those fumbles in critical situations.
"When you're going down, hey, secure that ball. Make sure you don't let the ball get away from your body anytime at any point in the game because with that you leave opportunities for guys to come behind you or get that lucky swing at the ball and punch it out. So that's pretty much what I meant," he said.
Peterson did have cornerback Zackary Bowman pulling on his facemask just before fumbling, but he wasn't using that as excuse for dropping the ball.
"That didn't have anything to do with the ball security. To say it's a facemask, I kind of seen it a little bit, but that still doesn't have anything to do with me holding onto the ball and me keeping the ball secure to my body as I go down."
Peterson said he has to have a short-term memory and put the fumble behind him. That was harder to do in the hours immediately following the game.
"I kind of beat myself up Monday night, Tuesday, and when I thought about it, I said, 'Hey, either you're going to bounce back or you're going to let this beat you up and affect you,'" he said. "I'm going to conquer and I'm going to prosper from this, put this behind me. The coaches and the players, they've been good motivating me. I appreciate it, but I don't really need the motivation."
