Keys to the game; Can the Chiefs start fast?? The Chiefs have two explosive players and how the Broncos handle those two will be the Key to the game! The Broncos love to play man to man so if Hunt or Hill catch the ball and break one tackle there may not be anyone else left to make a play. Defensively for the Broncos they have make Alex Smith make a mistake, Smith usually very good at taking care of the ball but the Broncos have to find a way to affect and make him uncomfortable. Game will be won in the trenches.
