Considering that the alternative to him were having two players who were poor ball-handlers, and couldn't run the offense in any fashion (Dooling and Bradley), I'd say this is not much of a distinction to make.
90% of teams in the nba dont even have a player who can run an offense, nevermind a backup who can.
You were drawing comparisons to players within the same team and their impact, which is directly correlated to their subs.
Actually I wasnt, I was simply showing that Rondo has a positive impact on the offense because some blame Rondo for our poor offensive output last year. I wasnt comparing him to anybody, only his presence vs absence.
Well you claimed it was the "biggest offensive impact on the team", so yes, it's a comparison to the impact of his teammates. And once again, this is a measure that directly correlates to who is subbing for Rondo when he goes out and takes upon his responsibilities. It's not the sole factor, but an important factor.
When Pierce came off the floor, you still had Ray Allen on the floor with Pietrus for example. When Ray Allen came off the floor, Bradley came in which high success in his SG role (while a poor success in the PG role when Rondo came off). So it all matters.
It's for this very same reason that part of KG's influence on the floor in a +/- analysis had him scoring on a high mark because there wasn't much of a substitute for him for much of the year.
As it relates to this year, I think the biggest impact we'll see is still KG's even though we've strengthened our big man rotation. I don't think Rondo will score as high this year with guys like Jason Terry and Barbosa ready to fill his role as needed.
