I'll add Rajon Rondo to the mix. Maybe Raja Bell. Devin Harris, too, but that And1 video says otherwise. Guards can be perimeter defenders, too.
Tony Allen is really good. Artest seems to give Pierce the most trouble out of everybody mentioned. Iguodala seems to be pretty effective from the little bit I've seen of him.
Is it morally right? Not really, but he gets in guys heads. He makes them miss. He gets under the other teams skin. And most importantly, he just fuggin wins. That's all that matters IMO.
Bruce Bowen has never been a good defender. If you have to try to injure people to play defense, your horrible.
?? Whatever gets the job done. Like I said before, Kobe said Bowen was the hardest defender he was facing (about 3 years ago). I think Kobe would know better than you or I.
