actually players in bot teams do get training, you just simply don't know which.
The bot team has (I asume) always the same starters and back-ups and trainingtype.
So if you have a player on the NT that is a starter in the bot team, he will get his minutes and stay in shape.
Ofcourse chances are bigger the player in question is not a starter .... (I guess 5 chances in 18 that he will be)
You do have a good point there, but I fear this will not happen, since it would make things too coplex, and to a lesser point also would make bot teams to weak (they loose their best player(s).
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
