The following are correlated with winning

offensive pass efficiency ((passing yards - sack yards)/(pass attempts + sacks) (Chiefs rank = 30 down from 27 last year)
offensive running efficiency (net yards per carry) (Chiefs rank = 28 down from 4th last year)
offensive interception rate (Chiefs rank = 7 up from 22nd last year)
offensive fumble rate (Chiefs rank = 29 down from 22nd last year)
defensive pass efficiency (Chiefs rank = 30 down from 29th last year)
defensive run efficiency (Chiefs rank = 21 up from 32nd last year)
defensive interception rate (Chiefs rank = 27 down from 22nd last year)
penalty rate (Chiefs rank = 22 down from 10th last year)
Relative to other teams, we are worse at running, fumbling more, and are creating more penalties this year.
On the bright side we are throwing fewer interceptions and stopping the run a little better.
