Warrior General Games

ok say i have 3 backs. i set the energy to:
min - 90
return - 95

so that i have basically a fresh back in at all times. My question is what happens when all 3 are below 90? does it run the highest %, or the starter?

starter - from what I've seen (I run 3 RB set-up at 98/99)

it will put the freshest player in
