Answer

$21,564\ yd$. No, see explanations.

Work Step by Step

Given $R_1=18,355\ yd$ rushing, $R_2=3224\ yd$ receiving, and $F=-15\ yd$ returning fumbles, the total yardage can be found as $R_1+R_2+F=18,355+3224-15=21,564\ yd$. This number is different from the sum of the absolute values of the three categories because $|R_1|+|R_2|+|F|=18,355+3224+15=21,594\ yd$
