With Kobe playing 10 feet off of Rondo, they cannot have him just dribbling into Kobe as he sits in the lane. It just won't work. In the open court, yes, attack, but in the halfcourt, Rondo is going to have to be playing off the ball, looking for holes in the "zone", and exploiting them by hitting the layups he gets, and finding the open men, when the defense collapses, after he catches the ball in the paint. He is also going to have to exploit the lack of attention by grabbing offensive rebounds.
I think if the C's are going to win, they are going to need Rondo to grab 10+ rebounds, and I think at least 5 of them are going to be offensive.
