It doesn't really matter. I've already said I'd acknowledge that given the disparity in opposing talent LeBron could arguably be ahead of Wilt.
Wilt averaged 17 rebounds per game against Kareem, and Wilt was past his prime in all of those games.
But with the above consideration in mind neither LeBron or Wilt would be in my top 3.
*Edit* But when you consider Wilt playing against Kareem, I don't think there is any way LeBron does that well. Maybe scoring wise, as LeBron has a far superior perimeter game, but everything else is all Wilt.
36 year old Wilt blocked mid 20s Kareem 17 times in a single series. Blocked Kareem 7 times in one game, including the skyhook twice. At 36 years old.
I think Wilt was a bigger force than LeBron. But LeBron does have a better perimeter game, so I get the argument that they are close.
I have Wilt up there as #2 because of his insane numbers and total dominance on a consistent basis. But take that away for arguments sake and he drops to top 5-ish on my GOAT board.
