I already told you what I did. I would say going something like that but maybe scaled down (mine was pretty drastic) would be the best way to experiment with this. It actually expands the range of each rating that is used. Primary positions from any position are then spread from being like 80-99 to being like 61-99. If the spread started out being more then it ended up being even more drastic. I would say something like even half my scale would show some pretty drastic results. Basically, guys who are 99 in an area, leave them. The lower a guy is in an area the more you lower them.
Now when EA does this they will actually be passing judgement on these players deciding what their ratings should be. In mine I just went off of the ratings EA already had and adjusted from there other than tom bradies throw power. There is no way I could justify leaving that rating that high.
