I'm sorry if this has been asked before.

I've already decided to tank it because of the bad start. I've started winning recently though and I'm already at 5th place. Because of the bad start, I'll probably end up 4th-7th. I've thought about playing my starting 11 at a different position so they can be better for next season. Will their skill gain be the same or will it decrease? If it decreases,by how much? If the decrease isn't too much, I think I'll just do that. If it's too much, I'll just take sub some of the players.
