How Do I turn On Stamina?

cuz you knw how theres stamina bars and stuff, but without Stamina i never use Subs and I want this game to be more realistic. So could someone tell me how to turn it on? I know how to turn the stamina bars (under the name when you sellect them while playing the game) but that doesnt help. Please help. Thanks

What I do is under Global I turn the Fatigue effect to 60 and I turn the Substitution Frequency for Human and CPU up to 70. I just finished a game where every player got minutes except for one on each team.

Yeah but...does that actually make their stamina go down?

Yes. That's the only way.

I find that Fatigue set to 50 and the default simulation slider setting for CPU Subs is pretty realistic. I don't use auto subs though, so I leave User Subs at 0.

I use auto sub and at first the 50 fatigue effect and 50 substitution frequency was cool but later I realized that players stayed out too long. So, I upped it to 60 for fatigue effect and 70 for substitution frequency for Human|CPU and now the starters will come out, get a rest and get right back on the court.

Ok then, thanks a lot
