Nah.
When Nash won those MVP's he was getting as many assists as Rondo, but also scoring 17-19 a night while shooting RIDICULOUS percentages of 50%/44%/90% ... Rondo is a great point guard, but he's completely unreliable on the offensive end. He can pass and play solid defense.. and run an offense as well as anyone in the league... but he lacks the ability to create his own shot or score consistently... a skill that point guards (equal to him in playmaking) like Chris Paul, Deron Williams and Nash have.... and point guards (less than him in playmaking) like Rose and Westbrook also have.
Rondo did have an amazing playoff this year, though. But he's had huge series in the past (2009 comes to mind) that didn't translate to huge regular seasons.
The idea that Rondo can not create his own shot is absurd. I would say "did you watch the playoofs?", but since you mentioned them in your post I know you did which leaves me wondering what you are talking about. It is true that he doesnt score in the high teens consistently but I believe it is commonly recognized around the league that he doesn't try to score big every night- only when it is needed. Steve Nash has never averaged more assists in a season than Rondo did this year. The most he ever averaged was 11.6. Paul, Williams, despite being very good playmakers, are nowhere close to Rondo as far as being a set-up man.
Rondo's best: 11.9 points, 11.7 assists 45%/24%/60%
Nash's best: 18.6 points, 11.6 assists 53%/45%/90%
Paul's best: 22.8 points, 11 assists 50%/36%/87%
Deron's best: 18.8 points, 10.5 assists, 51%/40%/80%
You figure if Chris Paul is scoring 22.8 points and 11 assists... that' means he's minimum responsible for 44.8 points per night, right? Likely more if his teammates are scoring threes. If rondo is getting 11.9 and 11.7... that means he's minimum responsible for 35.3 points per night.
Do you get my point? All of those guys are more consistent scorers than Rondo. If they only needed to score 12 a night, they could easily get more than 11 assists. They already proved capable of getting 11 assists while scoring far more consistently than ROndo likely ever will be able.
So you're saying that if you look at the stats for these guys, when their scoring goes down their assists go up?
You can't possibly say that Rondo's 11.7 assists is more impressive than Nash's 11.6 assists. That's just ignorant. Nash scored 18.6 points, because his shooting percentages were RIDICULOUS 53%/45%/90%... If he was a subpar scorer like Rondo, then he presumably would have taken less shots (or he'd be a detriment to his team)... in which case, he would have made up for the shots by using offensive possessions to rack up more assists... and thus... would have averaged more assists than Rondo did last year. The point is that as the hall of famers fade away from the Celtics, Rondo will be asked to score the ball more. If he's asked to score the ball more that means he'll be taking more shots. If he's taking more shots that mean's less offensive possessions to get assists. Less offensive possessions to get assists = less assists. This isn't rocket surgery.
That would mean that Rondo gets a lot fewer assists a game in the playoffs, when he takes significantly more shots? It might not be rocket surgery, but clearly things a little more complicated than you think they are.
Tim... I already know what you are alluding to. I smell the bait. I made the statement that if Rondo scored more/took more shots/used offensive possessions to take more shots... his assists would go down.
I already know your rebuttal will be to point out that Rondo took more shots in the playoffs and scored more points (17.3) while averaging more assists (11.9) and thus believe you are proving me wrong.
So you're claiming that you already know what I've already said? Exciting. But did you already know that I was asking you to back up your claim that when Deron, Nash and CP3 score less their assist totals go up? It's in the post as well, I guess you psychic ability needs a little fine tuning.
Nope. That's not what you were going for. But nice try. 
It's exactly what I said:
"So you're saying that if you look at the stats for these guys, when their scoring goes down their assists go up?"
I just made it into a seperate response because you clearly ignored it the first time. But nice try.
No I'm telling you that Rondo gets so many assists, because he can't can't score as well as the other great point guards who are better than him overall. If he tried to start scoring 20 a night (as those other point guards do effortlessly), he wouldn't lead the league in assists. Unless a player is truly elite (Nash in his prime... Chris Paul), you can't have it both ways.
Here's my problem with your insistance that Rondo's assists would go down if he tried to score more, you have very little, if any, evidence to back that claim up. It's pure speculation.
We do have evidence, although limited in sample size and in larger minutes, that Rondo CAN and HAS upped his scoring while maintaining his assits in the playoffs. He's never really tried to score more in the regular season, because it was in the best interest of the team for him to be more of a playmaker/facilitator.
All of your statements are mere speculative opinion. It's my opinion your opinion is wrong. But hey, that's what blogs are for, right? 
That limited sample size you bring up just proves me right, actually. His numbers were inflated, because he was averaging significant more minutes in the playoffs. I've been over this already.
Regular season: 36.9 minutes - 11.9 points, 11.7 assists, 10.8 shots
Post season (adjusted): 36.9 minutes - 14.9 points, 10.3 assists, 13.6 shots
Regular season (adjusted): 42.6 minutes - 13.7 points, 13.5 assists, 12.4 shots
Post Season: 42.6 minutes - 17.3 points, 11.9 assists, 15.8 shots
More shots = less assists.
Your "small sample size" just reiterated my point. Tommy point. If the post-big 3 offense relies on Rondo to score significant points... it's unlikely he'll continue to average as many assists.
