So you're saying Brook Lopez is a better defender on the perimeter than Charles Barkley? Because I asked you this before and you said that wasn't what you said. You're speaking in circles right now.
I have no idea what train of thought you are on if that is what you are getting from this.
EDIT: Okay, I think you are getting thrown off because you talked about Mutombo and Mourning on the perimeter, and I said comparing strong rim protectors / paint defenders was hardly a genuine comparison. And then I pointed out that a similar concept would apply to Capela and Brook, comparing them to Mutombo and Mourning in terms of approximate defensive role. Not the hypothetical where they go out on the perimeter while Barkley remains parked in the paint.
None of what you're posting is any type of proof Barkley will be worse defensively in this era.
That is literally impossible to prove. I have neither a time machine nor a cloning machine. Come on. All we can offer is rational arguments; there is no “proof” for how different players would respond to significant era changes.
You know what Barkley will benefit from tremendously in this era? The increased emphasis on help defense. Bad defenders don't just get isolated on each possession up the floor now to force a hard double or mismatch.
Mm, that is an okay counter in part, but I do not think there are strong indications that “help defence” prevents poor defending bigs from being playoff liabilities, at least not to the extent I feel would need to be true for Barkley to be an equal negative to what he was in the 1990s.
IDK which it is but you haven't even attempted to argue his defense would be worse now so...
... Do you just skim everything I write?
