Everything you just told me is a guess.
Obviously I can only guess, because I don't know your player skills and your opponent player skills. So I had to use the game stats and ratings to determine why the outcome was what it was.
Your assertion that maybe the last play was the other team "testing out their experimental play" or that my guys "quit guarding" is utter hogwash. The fact that you would try to convince me that the sim is so advanced that it allows for such things is poppycock.
You need to think creativly. Picture your guys going for dunks, steals etc. There will always be few of those presentational errors, that does not mean it's a bug.
the point of this game as I now see it is to train your guys up as best you can, sell them for money to buy experienced players and then train stamina every week.
This sentence shows why you can never succeed. You lack basic knowledge of the game. Looking at the players you have bought, arena you have built. Do you even know what staminas cap value is?
