Ok we're going to stop at around 40 characteristics and then vote some off to bring it down. Then we're going to take about 20 of the best players of all time and rate them on a 1 to 4 scale in every category. But we still have several missing (driving ability, boxing out, passing, floaters, toughness, etc) Again I don't want this list to be mine only, so let's get everything in and then we can get to the official celticsblog greatest player ever rankings.
