Basically, your players ratings will change slightly after each game. It's still based on the 5 groups of players (left, right, halves, front row and assists). If your group outplays their opponents in a game, their ratings will increse slightly. Likewise they will fall slightly if they are outplayed. Game plans affect this, and so do interchanges. Therefore, areas of the field that you boost either through game plans or interchange (or tokens) will most likely improve, while neglected areas may suffer.
So, for example, if your front row is slowly losing points, you can boost them (by ordering an attack or defence, or interchange) in the hope that they regain some stats.
If their points slip low enough, you can drop them to the PL side, and replace them. In PL, they are subject to form as well. Against weaker players, you could run them into form. Or you could put them on the injured list, and they will regain 10% per week off. Just remember that an injured player can only get back to their original rating that they had at the start of the year. You can't put your 4 5 PL bench halfback on the injured list all season and have him ready for the finals as a shock tactic with a 10 10 rating.
