Ok so we are aware that in most cases the players brought in at Academy level are not the greatest however there should be an option during the year to simply remove players deemed below the expectations.
e.g. you gain 4 new Academy players each season and can decide whether or not to offer them contracts each year.
My suggestions is to have the option to essentially say "your not good enough" and remove them from the Academy and await another Academy player. this will also assist as it does in football by providing home grown talent for future seasons.
Thomas, i am not sure what this would gain. Academy players are on a 2 year scholarship. So your academy manager will tell you the best 4 players he has from the players who scholarships is ending. Once it ends they become free agents or you sign them. Removing them earlier is like cancelling their scholarship but doesnt really have any benefit as you won't get 4 more until the next season.
Hope that makes sense. 2019 version will have a different system, but i can't reveal anything at the moment
