Well, gentlemen, don't be too surprised if after the coaches make their selections, KG isn't on the 1st team or 2nd team All-Defense teams.
I know, I know. They are just head coaches in the NBA, what do they know? Obviously they don't understand how all these advance metrics show that a guy that they all think is clearly not the best defender at his position anymore, clearly is.

First of all, you're gloating about something that hasn't happened yet. Secondly, even if those coaches agree with you about KG, it's fairly likely that they won't agree with your assessment of Rondo.
I never inferred that the coaches were better judges of talent than me, just better judges of talent than those advanced metrics.

I think that whoever they vote for would likely come from the list supplied (TD, AV or Josh Smith) and I think that most of the all-defense team will come from that list.
Look at the team we have, though. Paul's been slowed by injury since Xmas. Ray's defense was a big reason people wanted to trade him. People haven't been happy with Perk's play on either end of the floor for two months or so. Baby's defense hasn't been all world. Sheed's hasn't been good either. Eddie and Nate haven't been doing much on that end of the court. You don't think much of KG's defense and you claim that Rondo's significantly worse than last year.
Yet, despite all of this, as well as visual evidence to the contrary, the Celts have spent the bulk of the season with the best or second best defense in the league. Who's play is responsible for that?
