Rondo didn't attack the rim any more last night than he did in the first game. He's also been very consistent in the playoffs. I also think that most other "superstars" don't have the consistency you claim that they do. I'm fairly skeptical that Rondo's your second favorite player on the team, given your comments about his effort and consistency and the way you constantly gush over KG. I'd also say that Rondo's your favorite player to watch in the context that your favorite thing to do during games is find flaws in Rondo's games.
I tend to agree on your first sentence though I wasn't counting plays.
What he did do early on is push the ball on the fast break, even if his teammates could catch up. He went Westbrook on them and pushed 1 on 2 fast breaks where he felt defenders couldn't get ready in time for him and it led to a lot of fouls.
Another change that sometimes happens is that when Rondo gets into the lane, sometimes he is clearly thinking pass first, other times he is trying to get a shot. Some people may confuse this with being aggressive or not while I would contend that both plays are aggressive as they are attacking the defense.
What was exceptional last night, apart from the full speed sprints to the rum on the fast break, were his decisions to NOT attack the rim (in agreement with your first point) and decided to get in position for open jumpers. In game 1, he did not adjust to what the defense gave him and they were able to cheat. In game 2, he made them pay.
I would agree with you that Rondo's effort is consistent, but his game plan varies, which is a good thing. And as happens with all players, effectiveness varies from game to game. That is going to happen with the level of talent and intensity at this point in the playoffs.
