Really it's not an issue at all having the majority of our better younger players in the lower leagues, The managers in the III leagues have a better opportunity to train these players than the higher leagues. The fact that we are so small means that most of the lower leagues are filled with bots which equals easy wins which means that training minutes are a lot easier to spread around.
For this reason I would say that managers in the lower leagues are probably the most important in developing good talent. Sure we all have a job to do, but with the bot teams not scouting these managers have a real good opportunity to get a good young player and turn him into a superstar.
