Basketball isn't all about whether you outscore the person you are covering or whether you pile up more stats. That was the problem when Rondo was getting 15 assists but we were losing. Rondo has been a good solid, albeit under the radar, point guard these last few games. To me, that is exactly what we need from him.
We don't need 15 assists, we don't need him taking 19 shots. If he tries to be something he isn't, it hurts the team. I really like this recent Rondo better than the 15 assists Rondo.
I read a ton of posts about how happy people are that the offense is less Rondo-centric and he isn't controlling the ball and looking for assists as much. When Rondo's assist streak ended we were 10th in the league in offensive efficiency, now we're 21st or so. We were 6th in the league in 4th quarter points per game when the streak ended, now we're 23rd. I'd rather see the team play the style of offense that leads to more efficient scoring but that seems to put me squarely in the minority here.
I think there's a difference between how the team has played overall since the streak ended and how the team has played since Bradley came back.
Mostly I think people are talking about the offense looking better since Bradley came back.
So the change in offensive rankings since the streak ended doesn't really speak to that.
Though I'm not discounting what you're getting at which is that people may be seeing what they want to see / having selective memories.
