I put together stats from games without Rondo and season averages as a team. As you can see there is almost no difference in both FG% or assists per game.
FG % , and Assists
Brooklyn 35-75 , 17 Assists
Portland 36-73 , 20 Assists
Milwaukee 34-82 , 26 Assists
Golden State 31-86, 18 Assists
New York 39-74, 26 Assists
Miami 36-88 , 24 Assists
Sacramento 39-73 , 22 Assists
Orlando 42-84 , 30 Assists
Clippers 36-72 , 23 Assists
Toronto 35-73 , 21 Assists
Lakers 46-87 , 25 Assists
(47.1%) , 22.9 Assists Without Rondo
(46.2%) , 23.2 Assists per game WITH Rondo
When Rondo went down a number of people said "who is going to make up for 10 assists per game" and argue that Rondo has the ability to get his team better shots. The answer is anybody (and everybody). It will be interesting to see how the next few games play out, but if the trend continues it may become clear that the Celtics are in fact, the exact same with or without him.
The paradox of having Rondo possibly making us better by adjusting to the new style is that it will make him "worse". If he is asked to share the ball more his assists go down and since he has a less than average mid-range game he won't be be able to take advantage of open looks he gets on the perimeter OR help spread the offense for others.
If Rondo is asked to adjust, his points and assists go down, and we keep on winning, is he an All-Star anymore? He will essentially become Avery Bradley with no outside shot and without the defensive skill. He is technically helping the team by being unselfish and a team player, but statistics won't show it. It will be very interesting to see what happens but I thought it was worth making a point of these items.
