You're just pulling our legs here, right? First of all, it's 17 (not 18) for 70. That's better than 4 yards per carry, and that's AFTER taking away his 3 huge runs. And you're arguing that that's BAD? McCoy had two (2) runs for zero or negative yards. They came on consecutive 1st- and 2nd-down plays. Yeah, they failed to convert on that single drive. The Chiefs stopped the run once.
