Pit Bulls Razor's Edge dogs problems?

It's been a while since I've looked at any Razors Edge pit pictures but the impression that I got was that they were breeding the beauty and grace out of the dogs in favour of size and m. Even if they aren't adding Mastiffs into their bloodlines, those weren't dogs I would ever call well bred pits. In particular I remember a picture of a guy hugging a dog that was WAY bigger than your average pittie is. Not tall but mive.
