after 8-9 years of playing in the NBA everyone already knows all they need to know about a player. chris paul/lebron/melo/dwight are not going to come out next year playing a lot better than they did this year, they are who we think they are. like where ever you have chris paul in your all time top ___ list, thats what he will give you for the next 4-5 years. the only way he can make a jump in all time rankings is if he wins a championship.
duncan is by far the greatest PF of all time, the one thing that sets him apart from his peers is his 4 championships
the skill level of 07 kobe and 10 kobe is pretty much the same, but the two championships put him into all time legendary status
if jordan didnt win after his return and only retired with 3 championships he wouldnt be the goat
most people have magic over bird in all time lists because 5 > 4
at a point in all players careers they will reach their primes and stop improving, the only way for them to continue to climb the all time ranks is to win championships
