JOHN McCLAIN BREAKS DOWN THE GAME

THREE KEYS FOR CHIEFS

The NFL’s No. 1 rushing offense that averages 163.5 yards has to control the ball and keep the defense fresh. Playing behind an injured line, quarterback Alex Smith must avoid the rush until his receivers get open. When the defense gets to Deshaun Watson, it has to bring him down and not allow him to make plays.

THREE KEYS FOR TEXANS

Quarterback Deshaun Watson has to be prepared for defensive coordinator Bob Sutton to try to confuse him. When the Texans reach the red zone, they have to score touchdowns and not settle for field goals. The defense has to set the edge, be disciplined and keep rookie running back Kareem Hunt from bouncing outside.
