i'm only playing 21 year 2034. and i've noticed that too. every player i let go did not do well. some hardly got a game. don't have an explanation other than AI cant train their players to improve. judging by how my asst Man allocates work among coaches i am not surprised.
previous version i played were 2011, 12,13 i remember regretting selling players in those cos they did so well after leaving.
