Martin: Well, LeBron James is the greatest active basketball player I suppose so the parallel in Westeros would be who is the greatest active swordsman. You can make a case for Jamie Lannister. You can make a case for The Hound or his brother Ser Gregor [Clegane] or Sir Loras [Tyrell], the Knight of Flowers. These are all first class Knights. Or even Ser Barristan The Bold [Sir Barristan Selmy]. These are all guys who are top at their own particular sport, which is swordsmanship and jousting, and all of the combat skills that attend knighthood.
