Ummm... this is a really dumb conversation but just to clear things up a bit.
Big guys (as in muscular) can look "fat" with certain clothes on. I can't speak for that guy above, but very lean and very strong powerlifters can look "fat", due to big abs, glutes, thighs and chest. There's absolutely a possibility that the mvpberto is that lean, but his build just wouldn't show it.
Just because you're thin and has a decent drop does not make you lean. People who are not into lifting tend to think that thin=in good shape=very lean. Not necessarily true.
Most people I know that run a lot, look slim and seem to be in good shape are probably somewhere around 13-16% with no real muscle.
