I also think the difference here between Bird/Jordan is in the definition of skill vs. athleticism. Jordan's athleticism was through the roof, and it was a large part of his overall success, both offensively and defensively. Bird, however, wouldn't be found running faster or jumping higher than many players of a similar build (of course he was still quite tall, which was a big advantage for him) and thus his success at both ends of the floor was more based on 'skill' and 'technique'. MJ was obviously still a very skilled player and one could definitely argue that it takes just as much skill for a player to use their athleticism as only one facet of a much more polished game, rather than completely relying upon it like we see so many players do these days. But I think the argument BballTim was trying to make was that while Jordan was skilled, very skilled, Bird might be the most technically proficient player to ever grace the floor by virtue of his great passing, shooting, rebounding, vision and positioning.
