DENVER -- Broncos coach Josh McDaniels could have tied up the game with a 48-yard field goal, but he decided to go for it on fourth-and-1 from the Cowboys' 30-yard line. Running back Knowshon Moreno tried to slash through the left side of the line, but he was met in the hole by linebacker Keith Brooking.
Cowboys defensive end Marcus Spears made the stop on third-and-1 and then Brooking completed what may end up being the biggest play of the game. Brooking still has a lot of power and he filled the hole before anyone could lay a hand on him. Just a huge effort play on his part. Then he head-butted two assistant coaches.
