Warrior General Games

I have a lvl 17 SS and a lvl 14(now 15)CB. The SS has 19 in stamina. the CB has 15 in stamina. Both play for the same team.
After winning a blow-out game:
(35 plays) SS 1tkl. Energy 45%.
(63 Plays) CB 1tkl, 3 PD's, Energy 65%

SS has 3pts more spd and 1pt more agi. Weighs 13lbs. more than the CB. I'm wondering why did the SS use up so much more energy than the CB?

The SS likely did more running, covered more distance.

If the SS is on special teams and the CB isn't...you have your answer.
