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.
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.
