Write an article that answers the following question: How many points did the Cowboys win by?
With Ezekiel Elliott playing on a last-minute stay of his looming suspension and carrying the ball 27 times for 93 yards and one touchdown, and Dak Prescott throwing two touchdown passes to Cole Beasley, running for another score and finding receiver Terrance Williams nine times for a game high 141 yards, the Cowboys notched their third straight victory by a score of 28-17 and improved their record to 5-3 at AT&T Stadium against the AFC West division leading Kansas City Chiefs. Two long touchdown drives in the second half lifted Dallas to the win after KC had taken command on an unexpected 56-yard Tyreek Hill touchdown catch and run with no time left on the 2nd quarter game clock, then KC following that up with a Travis Kelce 2-yard TD grab from Alex Smith at 9:11 of the third quarter to take its first lead of the game, 17-14. Dallas' two long TD drives were 12 and 13 plays respectively, eating up over 12 minutes of second-half game clock.
