Madden player rating

I don't know how you guys come up with player ratings but holly cow you guys need to step it up I see people on Madden that are like 80 overall that are definitely way way better then that then I see people who are like 90+ who aren't even that good like what are you guys doing how are you getting these rating I mean you guys got a lot of work with the ratings to do but overall the game is great just wish all of the players would get a rating they deserve not some bull crap rating that makes no sense and while I'm thinking about it how can some do just as good 2 seasons back to back but get lowered overall or how can some do better and still not get anything added to there overall. Like the rating system is just messed up in so many ways and honestly not everyone needs to be a 90+ player I get that but a lot of people you guys got overated and a lot of players you got underated. Thanks for trying but need more work.
