Here's some information for the box score scouts.
Overall, this game was strange because of the injuries (both quarterbacks got hurt, the top receiver got hurt, a top defensive player got ejected, and the chiefs got 3 touchdowns from a single receiver). So it's not going to have as much predictive value as a "normal" game. But we can still look at usage.
Williams averaged about 12 rushes and 5 catches last year. He had 13 rushes and 6 catches yesterday.
Williams had two goal line touches (a catch and a rush) and he converted for the only score. McCoy didn't get a goal line touch.
Williams had 6 receptions, McCoy had one.
I know most of you didn't watch the fourth quarter, because the television feed cut out due to a power outage in the network's van.
McCoy had 4 rushes for 21 yards and a catch for 12 through 3 quarters.
Williams had 6 rushes for 10 yards and a touchdown plus 6 catches for 39 yards through those same 3 quarters.
Darwin Thompson had 1 catch for 3 yards, his only target in the game.
In the fourth quarter of a blowout, where mahomes hurt his ankle, Hill was at an orthopedic trauma center, and Matt Moore was the quarterback for the Chiefs for the final two drives, McCoy had rushes of 19 and 31 yards, and 4 more rushes for a total of 10 yards.
That's not the "take away his two biggest runs and he didn't have a good day"argument, it's a statement on his usage. When they needed to run the clock out, Williams got 7 carries for 16 yards and McCoy had 6 carries for 60.
I didn't see anything that makes me think that Williams won't continue to get about 10 to 12 carries and 4 to 5 catches a week plus a good amount of goal line work. I think McCoy played pretty well and is earning a good portion of the work too. Williams got a lot more touches this week but that will vary and McCoy could get a couple more at Williams' expense some weeks. I was happy to see that Thompson didn't touch the ball. Overall this looked pretty ok to me.
