Some stats to ponder when complaining that Rondo is holding back the Celtics offense or isn't fitting into the offensive system:
In the 5 games Rondo has played in the Celtics scored 106 points per game.
Against Chicago the Celtics scored 106 points.
In the 5 games Rondo has played in the Celtics have averaged 25 assists per game
Against Chicago the Celtics recorded 25 assists.
The Celtics had a slightly higher shooting percentage against Chicago than when Rondo played in the other 5 games but that comes down to hitting 1 more three pointer and 2 more 2 pointers than they normally do.
The Celtics took 3 less free throws against Chicago and made 3 less free throws against Chicago than they normally do.
To me this signifies that for one game, a few players picked up the slack and the offensive system continued to work at a near league leading pace(the Celtics averaged the 2nd most points per game in the NBA and have the 7th highest offensive rating in the NBA).
Rondo has an offensive rating of 97, one of the worst on the team. His two back ups, Marcus Smart and Evan Turner, have offensive ratings of 94 and 97 respectively, meaning that, the PG position in this offensive system isn't scoring and doesn't have to score to make the offense as a whole very successful.
Draw any conclusions you want from these facts. To me they point to a player that is widely regarded as one of the best passers and floor generals in the NBA doing his job and making his team's offense very good and that for one game, some others picked up the slack because that's what players do when their best player misses a game, a tale as old as time in sports.
Did the Bulls pickup the slack without Rose?
You also make it sound it , it was a one time thing that this team was able to score so many points vs the Bulls without Rondo. That has not been the case though and the offense has looked good for the most part ever since the start of preseason (without Rondo and when Rondo sits).
Without Rondo, the offense works a little differently. Other guys get more involved. We get to utilize our bigs passing skills to the max. This is a bigger deal than most think here bc they get to pull out their man from the basket and guys have easier time to drive in to cut to the basket for a layups. Or drive in and kick it out for wide open jump shots. In addition the other option is for KO, Zeller etc. around the perimeter to set excellent picks and guys like AB, Turner have open looks to make their jump shots. Rondo gets these kind of picks , space also but is usually hesitant to shoot unless he is super wide open.
So the question is, if this teams offense functions with Rondo or without (my preference) what value is Rondo really adding? ...
Let me start off by saying that I am a Rondo proponent. I think he is a special talent, and I hope the Celtics resign him and bring home 18 with him as a key player. However, there is some truth to what people are saying. Before the season, I said I wanted this teem to play like the 2002 Sacramento Kings (in pace and style of play). And so far, they do resemble a Kings-lite.
If Rondo was a Mike-Bibby-type shooter, it would add a whole new dynamic to the team, but he is not. People are on point saying his off-the ball game (threat of shooting) somewhat limits the point we can reach. However, I think what Rondo adds to a team is consistency. I think the Bulls game was a little bit of an anomaly. The Bulls were tired, and we were one call on Kelly stepping out of bounds away from losing. Down the stretch, our offense stagnated a little bit, not necessarily in ball movement but with overall effectiveness. This is where Rondo comes in.
For all of his streaky shooting (which I see as much improved, but I know others would beg to differ), it has been a loooong time since Rondo struggled to get people open. This is invaluable, especially when the game comes down to it. That was the problem with my aforementioned Kings. When the game broke down, they kept passing the ball around like a hot potato with no purpose or definitive actions. Rondo, even though he doesn't look to score,
makes definitive actions that greatly increase the likelihood of a score. At his best, Rondo does this all the time and sprinkles the threat of him scoring as well, which puts him over the top. Rondo's seemingly fully-recovered quickness will also help this. So while the offense may on average be the same, I think the timeliness of the actions are huge.
EDIT: I also second what nickagenta said. Rondo is a great floor general for a fast-paced offense. (Remember when everyone was clamoring for that a few years back, saying, "Free Rondo," and all the like?)
