Do players get tired – if not, what are the stamina and durability ratings for?
There is no game to game fatigue – meaning everyone starts every game at 100% in terms of stamina (not necessarily health). The stamina ratings refer to their in-game conditioning. For example, playing a player with a 20 stamina rating for 35 minutes is not a good idea – he’ll stay in the game, but he’ll be tired and play worse. Durability refers to their likelihood of injury and if they do get injured, how quickly they can recover.
