On Thursday night, Vikings running back Adrian Peterson returns to the scene of one of his most frustrating performances. Peterson fumbled twice in the NFC title game (both were recovered), and he caused a fumble on an exchange with quarterback Brett Favre that prevented the Vikings from taking a 21-14 halftime leads following a muffed punt by Reggie Bush late in the second quarter. Peterson believes he has corrected his fumbling problem, based on studying film of his past performances. "I found out at times by studying myself that when I'm going down, I kind of brace myself with the hand that I'm carrying the ball in and that's leaving opportunities for those guys that are in there scraping and punching for that ball, gives those guys opportunities to make big plays," Peterson said recently, per the Minneapolis Star-Tribune. "I'm a pretty tough guy, so I just [need to] keep the ball high and just fall down. It is instincts, but when that becomes a problem you're able to sit there and say, 'Hey, I've got to eliminate doing this.'" http://profootballtalk.nbcsports.co...on-thinks-he-has-solved-his-fumbling-problem/
