Not really. Lock down usually translates to good man to man. For instance Pheonix Grant Hill great defender Phenoix as a team allowed to many points. Knicks Melo and Chandler Great defense Team allowed to many points. Boston Lock down Team Defense Man to man Rondo and KG great lockdown. Pierce decent Allen ASS!!
Lock Down translates to man to man. If you can stay on 1 man, fight through screens, picks, cuts, curls, etc. and stay on your defender in man... then in team defenses where you switch, or zones, you're
normally very solid at those as well. It doesn't reciprocate in great zone defenders are great man defenders (see Hasheem Thabeet, and Chris Anderson). Chandler is not great defense. The bar has just fallen that much in terms of defense at Centers. Right now, only Howard is truly, TRULY, a great defensive player at Center. But in the decline of centers where we no longer have, Ewings, Ilgauskas, Mutumbo, Yao Ming, Shaq, Ben Wallace, Marcus Camby, Jermaine O'Neal, Alonzo Mourning, Elton Brand, Emeka Okafor. Many of these guys are past thier prime, retired, had injury problems, etc. Dwight Howard is the only one left.
Al Horford, not better than most those guys, Al jefferson, same deal, Andrew Bynum, not a defensive center at all, Amare not a known defensive star... When Nene, and Andrew Bogut are among the cream of the crop at your centers... can you honestly say that the position players are getting better?
Grant Hill has a bad knee, and is slower than most people at his position, sure he can defend in the half-court game, but his defense in transition is not so great.
