If running the ball and playing defense is a recipe for success, the Kansas City Chiefs will have to improve greatly in the second half of the season. While the Chiefs (6-3) started the year fairly strong in both those areas, each has taken a step back over the past month. But the Chiefs are hoping they can fix their ailments quickly, beginning Sunday when they play the New York Giants at noon at Metlife Stadium in East Rutherford, New Jersey. The Giants (1-7) are 28th in the NFL in run defense, giving up 125.9 yards per game, and that could be the remedy the Chiefs need for a slumping run game. Third-round pick Kareem Hunt burst onto the scene in Week 1 against the Patriots with 148 yards rushing and he followed that up with 172-yard performance against the Chargers in Week 3. Through the team’s first five games, Hunt ran for 100 yards or more four times and scored four touchdowns on the ground. But he hasn’t had a rushing touchdown since Week 3 and after starting the season 5-0, the Chiefs have lost three of their last four. And in those losses, Hunt has averaged just 48 yards rushing per game. “Honestly, I could have 50 yards (rushing) and as long as we win, I’m happy,” Hunt said. Obviously Hunt hasn’t had much to cheer about lately. His production began to tail off when center Mitch Morse and guard Laurent Duvernay-Tardif went out with injuries. Morse missed five games with a foot sprain and Duvernay-Tardif missed four with a sprained knee.
