Yep.. Agreed. I think they should implement a "college" system.. there is a post in the suggestion forums that explains this more...
I think it would be cool if they made a youth team. Like all players had to be U21. So basically like the national teams, except now everyone would have one. And all those youth teams would compete in a seperate U21 league. Then, when the players are good enough, or 22, or if you need them, then you could bring them up to your actual team. I don't know if I'm crazy, but I personally think that would be cool.
