WHY IS MY 400 POUND player SKINNY WITH STANDARD ARMS?

why when I edit my player and make my QB 300 pounds is he still skinny? Did you all not include the body types like in NCAA and previous maddens? Will this be in a title update to fix this? In NCAA there are lean, standard, and skinny and heavy body types and in Madden there is nothing. I just edit the height and weight. I need to be able to at least change the arms. I paid around 70 dollars for this
