The -6 fumble return yards are added to the all-purpose yards when summing the absolute values.
Work Step by Step
The all-purpose yards is the sum of the rushing, receiving, and fumble return yards.
$12243+5611-6=17648$

$|12243|+|5611|+|-6|=17654$
The -6 fumble return yards are added to the all-purpose yards when summing the absolute values.
