An interesting thought. And curious to see what more knowledgeable posters than myself think.
But it sure sounds like Barnes is better than Favors at this stage in his development. Make no mistake, Favors was an excellent talent. But Barnes just sounds like (by almost every account that I've read) he is a rare player that is exceptional in most facets of the game.
Also, I tend to think that big men take longer to develop than wings, so Barnes may have a better opportunity to shoulder the load, so to speak.
Other thoughts?
