Oh believe me, a big body can only get you so far... After that you have to do your homework. It'll catch up with LeBron, trust me. Remember basketball is a physical, mental, and emotional game. If any of these are out of check (I'm looking at mental and somewhat emotional for LeBron), then you're going to be out of check. A good player has good physical presence, a great player mentally outwits his opponent while keeping his emotions in check.
