what does bill russell have to do with dennis rodman? one guy won 5 MVPs and the other averaged 7 ppg, so your reasoning seems...poor.

and what part of being the best rebounder (or shot blocker, or steal swiper, or 3pt shooter, or whatever) of all time requires your teammates to be good?

its literally only saying someone is the best at acquiring a single statistic, so what the fuck else matters except that statistic?
