MJ did it without needing to run full speed - infact, he stops on a dime and spins back in traffic - this is a superior display of skill and athletic ability.
If you gave Westbrook 3 more inches, more power and smarts, and the ability needed to triple his dunk frequency (as the stats show)
, you'd have Jordan.
Other than Jordan's vastly higher dunk frequency, MJ's advantages seem to be statistically reflected primarily in his considerably higher FG% - after all, Westbrook's per-100 possession production this season is only slightly less than peak Jordan's, but Westbrook shoots a whopping 10 percentage points less in FG%.
So imagine Westbrook doing everything he's doing now, but only bigger, stronger, smarter and the ability to shoot 10 percentage points better and dunk 3 times as often.. that's the GOAT.
