you can't rank defensive guards with centers
people will just rank mostly centers over guards because they think rebounding is part of defense and it makes them a better defender than a guard
also with blocks. when its actually bad defense to try and block an outside shooter
and steals are from playing mostly passing lanes as a roamer
true defensive skills are measured by watching the games
and defensive teams should count
for instance. one person ranked kobe as not a top 10 defensive guard all time. and hes got the most all defensive 1st teams in nba history
in his prime he was a lock down stopper. and its way harder to defend and score at the same time
guys who were great on both ends should get more credit than role players who used 100% energy on defense.
