Hondo was a phenomenal all-nba-defender for like, most of a decade. I'm not sure any of the other names really match up to his credentials.
That said, I'm probably somewhat biased towards DJ because I watched him out of the gates as a rookie when he was ridiculously athletic, flying all over the place for Seattle. He was not quite the same uber-athletic guy when he got to the Celtics -- though a case could be made that he was an even smarter, more effective defender overall.
Danny Ainge was actually another excellent defender who doesn't get enough credit sometimes.
