I actually think that westbrook > stockton if each player is their best. Westbrook averaged a triple double last year and won the mvp. I don't think stockton could handle his speed, power, and explosiveness I don't we have ever seen a pg with his speed, power, and explosiveness. (Maybe mvp D Rose)
Harden and pierce is about a tie to me though I'm pretty certain that if harden plays as long as pierce he will pass him in pretty much every statistic.
Pippen is much better than masburn.
I think the brow is better than barkley. Difference is that with barkley you have a whole career to look at how awesome he is. The brow is 23 years old. As a 23 year old he averaged 28 points and 12 rebounds along with 2.2 blocks per game. Shoots 80% from the line and gets there often and is a better three point shooter than barkley.
Barkley averaged 28 ppg once in his 16 year career. Both great rebounders, with the brow being the better defender (Especially with his length against short bigs that can't shoot the 3 like barkley), and barkley the better passer.
I get why you and others would knock the brow cause good career has been so short but again I would bet that if AD plays as long as barkley he will pass him statically in many categories.
I actually think the Shaq vs Alonzo matchup is closer than you do with Shaq of course coming out on top.
I think WC has the better bench.
The same argument you used for Westbrook against Stockton can be used for Barkley against Davis. Barkley is the only PF to ever average 25, 12, and 5 and he won the MVP that year.
