It's likely that a bit of the size /bulking up is steroid based, but a lot more is just based on the relative size of the population pool and the kinds of exercise and diet regimens used with a focus on size and burst speed. Where some sports will stop at a certain level then focus on stamina and maintenance, US football may keep pushing for more bulk.
