I think it still remains to be seen if either Sullinger or Rondo are good defenders, although I'm too busy to check their defensive numbers from this year right now.
Rondo's got about 7 years of better than average numbers to go along with his 4 years on all-defense teams. He has a couple of top 5 finishes for DPOY as well. Aside from all of that, it's a close call.
The issue with Rondo is he wasn't a plus defender his last healthy year. Wasn't putting the effort in consistently, in my view because of the huge burden on him offensively.
Add to that his injury and I'm not sure we're see all-defense Rondo again consistently.
I disagree with the assessment in bold.
Rondo played in a variety of 5-man units that season: Here are the 6 he played the most minutes in (the only ones with >50 minutes) and their defensive rating:
Min Unit DRtg (points per possession)
221 RR+JT+PP+BB+KG .99
122 RR+AB+PP+BB+KG .98
78 RR+CL+PP+BB+KG 1.15
77 RR+JT+PP+BB+CW 1.01
62 RR+JT+PP+JG+KG .91
53 RR+JT+PP+KG+JC .99
So, basically in the main units that he played in - which account for 613 of Rondo's 1423 minutes played last year, the team had an excellent DRtg in all but ONE unit.
The rest of Rondo's minutes were scattered across a wide variety of units with very small amounts of minutes and a wide variety of defensive ratings. Rondo was the starter who stayed on the floor with the various bench units the most through the first half of the season. Most of the 'bad' defensive minutes were from units used in the Fall that had things like a front court of Bass plus then-rookie Sullinger. A LOT of his bad defensive units had Courtney Lee on them. None of his best units (of significant minutes) did.
Lee was terrible at picking up help rotations in Doc's defense last year and ultimately got benched for it.
I don't believe Rondo was a bad defender at all last year. The team he was playing on had defensive struggles though. Especially when multiple veterans (KG, PP, JT, RR, BB & JG) were not on the floor. As long as their were 3 or 4 of those guys on the floor, things usually held together. But if not, things were often ugly on defense.
That's interesting.
In other news, Rondo's Drtg in 2006-2007 was 103. That dropped to 98 in 2008. I think we can figure out why. It climbed back to the hundreds for every year after that, (aside from 11-12) hitting 103 in 2009-2010 and 12-13.
His Drtg (small sample size of 9 games) currently sits at 103.
as an aside: His defensive win shares have also declined every year since KG's knee injury.
I know BballTim is fond of bringing up Rondo's all-defense awards, but my suspicion is that any defensive accolades for Rondo are squarely in the past tense, and help us evaluate his play in the present about as much as you might infer.
Which is really what I mean by "wait and see if Rondo's a good defender." A good/willing defender moving forward.
If your suggestion is that KG makes everybody a better defender, then I'm not going to argue against that.
But if you'll notice the top three units listed, it isn't the addition or removal of KG that is different in the one bad lineup.
KG may make everyone a better defender, but that doesn't mean others aren't good defenders and bad defenders.
Rondo's DRtg before KG may say more about how bad certain guys on that 2006-2007 team were on defense. Rondo was also a rookie that season.
Heck, I just did a scan on 2-man units from 2006-07 that got at least 200 minutes together:
RR+Gomes 885.1 109.8
RR+Delonte 217.8 103.6
RR+Perkins 785.8 103.5
RR+G.Green 904.9 103.2
RR+Telfair 392.6 103.2
RR+Scal 405.6 102.4
RR+Pierce 565.3 102.2
RR+Big Al 981.2 101.3
RR+A. Ray 437.4 100.8
RR+Powe 421.2 98.9
RR+Szczerbiak 209.9 98.0
Now, if you look in turn at Ryan Gomes' numbers, they are pretty awful:
Gomes+Scal 296.2 117.6
Gomes+Szczerbiak 568.9 113.9
Gomes+G.Green 934.6 113.7
Gomes+Delonte 1235.9 113.0
Gomes+Tony 334.9 111.4
Gomes+Pierce 930.0 111.9
Gomes+Big Al 1323.3 110.2
Gomes+RR 885.1 109.8
Gomes+Telfair 946.6 109.4
Gomes+Perk 901.5 108.8
Gomes+A. Ray 359.0 107.2
Gomes+Powe 230.8 100.7
Wow -- that's just bad. And he was on the floor a LOT! 2275 minutes for Ryan that season. Half of Rondo's minutes were with Ryan on the floor with him.
In the 946 minutes Rondo was on the floor in 2006-2007
WITHOUT Ryan Gomes, his DRtg was 96.6.
'Just sayin...
Aside: Kinda makes one pretty nostalgic for Leon ...
