So, in all the time I played this game in my previous incarnation...and my limited 2 seasons now, I haven't seen anything like this. All my players have had their Stamina collapse. Most of my team is playing at Stamina levels below Average. My Game Shape for all players but one is Strong or better. So, I am clearly not playing any single player excessively. Any suggestions, other than being forced to burn a week of training on "Stamina"? Never had to do this before, so what kind of realistic change in Stamina can I expect from a single week of "Stamina Training", or too many variables to estimate?
