NFC Wild Card Game: Minnesota Vikings at Green Bay Packers

FILE - In this Dec. 24, 2011, file photo, Minnesota Vikings quarterback Christian Ponder (7) looks up after getting tangled in the legs of Washington Redskins inside linebacker Perry Riley (56) during the first half of an NFL football game in Landover, Md. The best way for quarterbacks to keep from getting hurt when they're carrying the ball is to slide feet first, right? Well, the Vikings have persuaded Ponder to take a head-first dive instead. Offensive coordinator Bill Musgrave provided video evidence of his theory that it's the safer way to play. (AP Photo/Evan Vucci, File0
