What do you mean? Like if I took Dion Dawkins and made him a slot receiver without adjusting any of his stats?
I just did this in Madden. Dawkins is a 77 overall in my online franchise as a LT. If I change him to WR so I can play him in the slot his rating drops to an overall of 12. So, you can't just take players and move them where ever and not think their rating is going to suffer if you play them out of position. Now, I can go in and change all his ratings so that he could be an amazing receiver without changing his body make-up but I have to do that automatically. Also, if you're in game you can't just move a left tackle to WR, it doesn't give you that option, its something that has to be edited through a menu out of game and you have to officially change his position. Now, that doesn't mean that you can't change where he plays on the offensive line on the fly, as all those are interchangeable. I can move Dawkins to wherever I want on the line without having to edit his official position.
