And if you look you will see guys with 18 JS shooting under 40%. That is a bad shooter. So its not full training at all, unless your goal is to pay more salary and lose games.
40% is really high our best shooting team in our league(22 win with 4 looses), has none player last season above 40% with more then 10 taken three, and he didn't played inside which will crush shooting percentages additionally and in the german league many teams forfeit games which will push the ratings also.
I am not sure how the shooter look like, afaik some of them have high range but he managed to draft last so i won't say that his shooters are bad, but you need to live with lower shooting percentages here then in real life.
