I said "no big difference" as an LA I expect you to understand what I wrote.
Of course A will be better than B, but those skills are really not the core skills of a center so its not that bad if he lacks in one of those.
The difference between handling 1 and handling 8 is 0 for a center - those guys dont have to be the best ballhandlers on the court. Same is for blocking for guards, thats not their job, so they dont need it.
