What it means: The Chiefs went to 4-0 for the first time since 2003, and depending on the outcome of the later game between the Denver Broncos and Philadelphia Eagles, Kansas City will be no worse than tied for first place in the AFC West. The Chiefs also showed they could win without dominating the turnover battle for the first time this season. They committed three turnovers, their first three of the season, while the Giants also committed three turnovers.
Stock watch: Dexter McCluster delivered the game's biggest play late in the third quarter when he returned a punt 89 yards for a touchdown to break open what had been a close game. Two players plucked off waivers at the end of the preseason had big contributions. Rookie cornerback Marcus Cooper, who went to camp with the San Francisco 49ers, filled in nicely for the injured Brandon Flowers. Tight end Sean McGrath, who went to camp with the Seattle Seahawks, had five receptions, including one for Kansas City's first touchdown. Veteran cornerback Dunta Robinson, who opened the game replacing Flowers, was burned for a 69-yard touchdown by Victor Cruz before being replaced by Cooper. Robinson stayed in the game but as the nickelback covering the slot receiver.
Killer instinct: The Chiefs for the third straight week showed an ability to put away an opponent in the fourth quarter. Ahead 17-7, the Chiefs went on a 14-play, 80-yard drive that chewed up 9:17 and ended with Alex Smith's 2-yard touchdown pass to Jamaal Charles. The Chiefs later took advantage of a New York turnover to score a final touchdown.
What's next: The Chiefs play the Titans next Sunday in Nashville, Tenn. It's their only road game in October. After returning from Tennessee, the Chiefs will play home games against the Raiders, Texans and Browns. Their next road game after Tennessee will be against the Bills on Nov. 3.
