I have noticed that editing a player in the "Body" section will correct their true measurements. That is why they have unproportional body in game. I have tried also with the default Roster.
Just click one notch on one of the arrows for adjustment (i.e. "Body Length") and you will notice an abrupt change on their measurements especially their "Wing Length".
Some will make their "Wing Length" shorter and some will be longer. And then put all back to 50...even if u put all adjustments to 50 you will no longer see a big change.
I hope this will help everybody....
