Thanks for the article. Nicely broken down. Many reasons to love KG.
Still, and maybe I'm going overboard, but I think that even without KG in the lineup, we should still be much better than we are.
Many folks, myself included, seem to think the other 4 starters are either all-star or near all-star caliber players. Rondo, Perk, and PP are supposed to be superior defenders in this league in their own right. Thibs is still supposed to be a defensive whiz on the coaching staff.
Granted, the bench doesn't have what it takes to be strong defensively, especially any time House plays instead of TA (like against Jason Terry).
KG: take your vitamins, dude. We need you.
With respect, I think that we have now seen enough evidence over the last three years to make a more informed judgment about the source of the Celtics' defense. In 07-08 a large majority of people credited KG as the source of the Celtics' historic D, and it resulted in him winning the DPoY award. But there was also a pretty solid and growing push-back opinion that it wasn't actually just KG, but it was instead Thibs' defensive scheme and other strong defenders such as Perk, Rondo and Pierce that had as much or more to do with the great Celtics defense than Garnett did.
Then last season happened, and KG got hurt, and when he did the defense absolutely fell through the floor. It went from elite-best-in-league to average-or-worse for a good third of the season as well as the postseason. All of the other elements were still in place...Thibs still coached, Perk/Rondo/Pierce were still on the court, but the defense stunk.
I thought that should have been proof pretty positive that Garnett was by-far the biggest reason for the Celts' D, but there is still a pretty vocal segment that don't agree. I've seen posts and articles in many different places suggesting that Perk is now the anchor of the defense, that Garnett is still good but the injuries slowed him to the point that now he's just another cog instead of the lead dog, etc. But...
Yet again, when KG has been hurt the defense has fallen through the floor. It's like clockwork. And it's not a short-term effect either, because as I (and the article in the OP) pointed out it happens every year when KG is absent. As such, I think it's high-past time to recognize that Perk, Rondo, Pierce, Sheed, etc. are not defensive impact player. They can be solid defenders, good defensive role players, but they aren't good enough defenders to actually form a good defense even when working in tandem. Likewise, Thibs' system is good but it only works if KG is here.
It's no disrespect to any of the Celtics players or coaches to say that the Celtics defense just isn't going to be good with Garnett, anymore than it'd be disrespectful to Gasol, Odom, Artest, Bynum and Phil Jackson to say that the Lakers' offense wouldn't be as good if Kobe were out. It's more of an indication that KG's impact is really that big, on the order of what many people consider to be the MVP-level players of the league, despite that his box score numbers don't look like they used to. Even among Celtics fans these days...perhaps ESPECIALLY among Celtics fans, I think Garnett has become dramatically undervalued as very few seem to acknowledge or realize that we still have one of the top handful of players in the NBA on our team...at least when he's healthy.
