Cowboys get the kickoff, Murray runs it 7 consecutive time and gets down to the 20, where the running game is abandoned. First down, holding penalty, 2nd down sack, 3rd down 2 yard pass to Witten. Baily attempts a 51 yard FG and Cowboys take their only lead of the game. Murray gets 5 more carries the rest of the game. The cowboys fall behind on Denver's fist possession, and eventually Romo goes to the no huddle, (we don't have a hurry up offense).
Denver wins 24-17, with the Cowboys getting a defensive TD, and one in garbage time. for whatever reason, I see Manning having an off day.
One last perdiction, there will be as many Broncos fans as Cowboys fans, but the Bronos fans will be much louder.
