We basically have three years of proof that the team wins more when Rondo sits. Check the win loss records. We lose his playmaking ability, but having competent scorers out there is a powerful thing.
We were dreadful last year in games rondo played. I think we won 3 out of 33 games or something.
The year prior we were under 500 until rondo got hurt and the team rallied and made the playoffs.
Rondo is a terrific player and can be big in the right system, but his contributions are a bit overrated.
i was perhaps the first poster to broach this topic consistently here and the numbers you cite need deeper analysis. yes, in the celtics w/l record over the past 2 seasons + 6 games the celtics win more without rondo than with him. but, not dramatically so. last year is hard to count (or needs to be counted very carefully) given his recovery from injury. this year, he did not make training camp and it is, after all, 6 games.
the way i put the conundrum was to ask WHY the celtics w/l record does not reflect what rondo is supposed to bring to this team, an improved offense and defense and thus more wins. any possible answer can NOT be provided after 6 games this season, but only at mid-season or later.

For a number of reasons I don't believe there is a whole lot of value to those numbers without going into detail about the context. To me there are way too many variables, and it isn't that simple.
1) The main reason I disagree with this approach is you are trying to compare RR's impact on different rosters from very different years where there is a significant change of the other players on the team, the coaching staff, the approach to the season. They were vastly different teams, yet you are trying to extrapolate data as if the only difference was if RR was playing or not. That isn't the case.
2) The record itself tells us nothing about the context for those games. Who else was out for the game, what games were 2nd night of back to backs, who were the teams they were playing, did we get on hot streak, were we already in the middle of an extended time of overall poor team play.
3) In 2013-2014 RR was coming back from an ACL injury. It is widely accepted, from both DA, BS, and the team themselves that Rondo wasn't completely recovered. He wasn't playing on a consistent basis, playing a night on, taking a night off. He wasn't recovered. We were a very bad team as well. So the year with the biggest % change in wins and losses with or without Rondo is a pretty flawed stat, unless you think he is never going to recover from his ACL injury. I don't think most people would judge a players value to their team based on games they played when recovering from a significant injury. It just isn't a reasonable assumption.
4) Not enough sample size in 2011-2012, 2014-2015.
5) In 2011-2012 we were 11-9 in the playoffs with Rondo playing and making significant contributions to us nearly getting back to the nba finals. In 2012-2013 Rondo was injured and we looked terrible in losing in the first round to the knicks 4-2.

2012-2013 playoff record w/out Rondo 2-4
If you are going to claim that we are a much better team w/out rondo, then the won loss records in the playoffs should seem to be just as an important stat to consider.
I for one, don't claim that Rondo is the best point guard in the nba, I don't claim that we can't win without him. But I disagree with the logic of trying to take out small samples of data from multiple years where the teams, coaches and approaches were vastly different and try to place reward or blame all on one player.
