I'm not sure why you feel any of that was a knock against him, unless you think he was a modern day player time traveled back to that era. Modern era players have had sports medicine to make them better athletes. Imagine if he was trained the way modern players are. Monster. He didn't just have his size to overpower defenses. He had quickness, great hands and vision receiving out of the back field, and could even throw nice passes out of half-back options. If he were trained in the modern era physically, he would be scary good.
