At least with experience, i.e., playing in games, players should at a minimum improve the AWR, which I believe is one of the key attributes of each and every player. Someone else said, they would not play there backups as much, because they improve in season at all. This makes sense! Why not just turn fatigue off and run it like an arcade game, if players aren't even going to become a little bit more game smart during the course of a season. I liked it when you might have a player go down injured and you slot someone else into their position and over the course of four weeks or so, they would become a better player than the one sitting on the bench with an injury.
Bring back in season player progression for Dynasty mode!!!
