of the 180, maybe a third have allstar+ potential and maybe half of these have sufficient starting skills (any 18yo or a 19yo with 55+ tsp), so that's like 30 players. Of these 30 players, you need at least 10 to be trained to get a starter + backup lineup 4 years later. The numbers speak for themselves, if you got only 2 or 3 managers involved you're in trouble, and you need 10 players EACH season.
I understand that you can't really do that in big european nations but come on, it's a 1hour job once every 4 months. And it's just to get the ball rolling with the managers.
