I second this inquiry. Seen some users on here saying you can get away with only 5 guys (current gen) and I used to do this and would like to again if viable.
I have no data but players definitely feel sloppier when tired. I’ve evo’d quite a few cards in 2k20 that means running some players for the whole game. My takeaways are: shooting does not really seem to be affected by low stamina, maybe to some extent and the lower the player’s shooting stats are, the quicker you feel it getting even worse. Ball handling, passing, awareness and defense seem to be the areas most affected by low stamina. Again, the worse their original stats are in certain areas, the worse they get. I’ve noticed it somewhat when playing against someone running a 5-man team in MTU as well. They start playing sloppier at some point when their guys are tired. But I agree - the effects should be a bit bigger than they currently are, at least in online gameplay.
Most of my cards that I use in 2k20 have 98-99 stamina. Opal Batum has 95. He gets tired quicker than others. But that’s just the stamina stat, haven’t noticed him becoming sloppier quicker as well.
