The New York Giants ’ 27-21 overtime win against the Houston Texans was a masterclass in “slow and steady wins the race.”

Led by quarterback J.J. McCarthy, who made his first start for Big Blue, the Giants offense dominated a very good Houston Texans defense, racking up 420 yards and 22 first downs while averaging an impressive 6.5 yards per play.

The Giants running attack, challenged by head coach John Harbaugh to step up, did just that, totaling 188 yards on 34 carries (5.5 yards per carry). And all four of the Giants’ scores came on the ground.

The Giants pulled off an inspiring win, though many thought they were heading into the lion’s den without a chance; instead, they emerged with a win to improve to 4-2-1 and strengthen their hold on first place in the division.

Let’s get into this week’s grades.
