fatigue

how do you make players like yao ming get subbed in and out like in real life on the game he hardly ever get tired what rating should i put down to make him get tired hardiness or endurance or some other one

first lower the strenght of the player
then lower his endurance

make sure to lower his endurance 50% of his normal conditions
(just to make sure that he is sub...hehehe)
but it works...
