JUST SKIP TO CONCLUSIONS BELOW IF NUMBERS MAKE YOUR HEAD SPIN
There is a site called nbawowy.com which provides detailed info on what happens when various players, or combinations of players, are on/off the court. Given various comments both here and from Karl, Cuz, etc., I wanted to see what the numbers said about the performance of the rest of the team with and without our main guys, Cuz, Rondo, and to a lesser extent Gay and Collison.
There will be 4 stats used below. NBAwowy produces hundreds of stats, but I'm not going to reproduce the whole statistical package, and this may get cluttered as is. The four stats that will be included:
Stats Used
1) TS% -- hoary scoring "efficiency' stat taking into account FG/FT/3pt
2) %Ast -- the percentage of a player's shots that were assisted
3) Scoring Index (SI) -- an NBAwowy metric based on a general 1 to -1 scale, with a "0" scorer being a guy with 54%TS and a 20.0 usage rate. I checked numerous major players, and the accuracy of the stat was impressive at higher levels (think it breaks down for roleplayers), so I'm including it as an overall scoring effectiveness metric.
4) Team Off/Def and Net Ratings -- calculated by multiplying NBAwowy's PPP stats by 100
We'll check effectiveness of each player and the overall team through various combinations:
Part I -- Team Off and Def Ratings With and Without Our Main Cogs
Team
Overall: 106.5Off + 109.0Def = -2.5Net
w/Cuz+Rondo: 108.5Off + 106.3Def = +2.2Net
w/Cuz, no Rondo: 106.7Off + 108.4Def = -1.7Net
no Cuz, w/Rondo: 101.4Off +116.8Def = -15.4Net <--!!
w/Collison+Rondo: 107.9Off + 111.0Def = -3.1Net
w/Collison, no Rondo: 108.2Off + 109.5Def = -1.3Net
no Collison, w/Rondo: 105.2Off +108.2Def = -3.0Net
w/Cuz+Collison: 110.0Off + 108.1Def = +1.9Net
w/Cuz, no Collison: 105.6Off +105.3Def = +0.3Net
no Cuz, w/Collison: 106.1Off + 112.5Def = -6.4Net
w/Cuz+Rondo+Gay: 108.3Off + 104.7Def = +3.6Net

Part III -- CONCLUSIONS
1) Rajon Rondo is NOT a defensive problem....unless you take DeMarcus Cousins off the floor. Then there is a staggering collapse. In fact, Cousins and Rondo together created one of our best defensive pairings, with a Defensive Rating 2.7 better than our season mark. The entire damage to Rondo's defensive rep happened when he was out there withOUT Cousins when...holy hell. Units with Rondo on the floor without Cousins were absolutely 76ers level terrible. And you add those numbers in , and overall Rondo's D looks bad. But when he was out there with Cousins, we did about as well as we could do last year. In fact better on defense than we did with Collison and Cousins out there.
2) I really wanted to take a look at Karl's perception that Gay can't play with Cuz, and that Cuz/Gay/Rondo don't work...and it turns out to not be true at all via multiple metrics. In fact when the three of them were on the floor together, our Net Rating was +3.6. For comparison the 48-34 Hawks and Celtics were at +3.1 (ATL) and +2.5 (BOS) on the season. The 53 win Clippers were at +4.2. In other words when Cuz/Rajon/Rudy were all on the floor together, there were playing at a 50-win level.
3) Not only that, but while he got fewer shots, Rudy absolutely thrived playing alongside Rajon and Cuz with a TS% nearly 50pts higher than his overall season. Like Rondo, Rudy's perceived struggles were not when he was out there WITH Cuz+Rondo, he failed and pulled down all his numbers when he WASN'T. When Cousisn and Rondo were out there together his TS% was an excellent .583. When neither Cuz or Rondo were on the floor? A pathetic .474. That's a gulf so broad its almost impossible to misinterpret it. Gay not only works with Cuz and Rondo, he NEEDS them.
4) Almost the entire lineup thrived with Cuz+Rondo both out there, but in particular Marco (91pts higher, and a .591TS% when out there with both those guys!) Willie and Acy with 49pt and 85pt jumps in TS% and massive jumps in SI rating, and Seth Curry, who's % of assisted shots shot upward from 59.8% to 80%, and who's already very nice offensive numbers turned stellar.
5) I think Marco deserves a separate entry for that: His TS% without Cuz and Rondo = .500 (which is bad). His TS% with Cuz and Rondo both out there = .591 (which is potent). There's a defensive issue, but those numbers argue very strongly he should have been starting.
6) Surprisingly the one guy who really did NOT do well with Rondo and Cuz? Omri. He was flat better when not out there with those guys. Combined with Kosta and Collison getting relatively shrugworthy bumps, and having lower SIs as their shots were siphoned off to Boogie, and you had a fairly natural starter/bench split.
7) While Rondo may be "Cuz's PG", and indeed helped him marginally with a few more assisted hoops and a little better TS%, the real power of Rondo and Cuz together was for their teammates. This BTW was my initial hypothesis that I started this whole mess testing out. grew from there.
Part IV -- Testing The Numbers
According to those numbers, any of these lineups would really work:
Cousins
WCS or Acy
Gay
Belinelli or Curry
Rondo
In other words, a shooter at SG, and a defensive/hustle PF next to Cuz. So I went and checked each lineup:
Cuz/WCS/Gay/Marco/Rondo = played 45 minutes all season long, got destroyed 79-112
Cuz/Acy/Gay/Marco/Rondo = played 5 minutes all season long, won them 11-6
Cuz/WCS/Gay/Curry/Rondo = played 16 minutes all season long, tied 31-31
Cuz/Acy/Gay/Curry/Rondo = played 40 minutes all season long, won them 98-79
Hardly conclusive, but it is remarkable that our 4 most reasonable lineups (according to the numbers) around Cuz and Rondo collectively played barely over 100 minutes between them.
Alright, that's enough to chew on now. If you want to play, go to NBAwowy (and its crappy, clunky, error prone interface) and run searches to your heart's content.
