I'm not gonna penalise guys who signed up before the player ratings were changed because no-one wanted to give him a contract. That'd be even harsher imo. That's why I bought in two new teams, the amount of FA last season was massive. Most of those though registered after the first ratings change however and are rated lower as a consequence (for the reason you gave in your post).
There are only a handful of players in that catergory and it shouldn't really effect their performance if they remain active.
