Chasing the basketball has nothing to do with the flow of the offense.
For this offense to succeed, Rondo HAS to be aggressive with the basketball. Not once a quarter. Not twice a half. Most of the time.
Instead, he's fiddling with the basketball - as were West and Arroyo - in the first half, killing the ball movement and the motion offense. The point guard play in the first half was atrocious, and played a big role in the stagnant offense. Clearly, Doc saw that and hopped on Rondo at intermission, because he did a better job attacking with the ball in the second half. Not good enough, because he's a talented enough passer to attack the defense EVERY time and make something happen, rather than launching a jumper that's not going to go in.
Cannot have it. He has to play more aggressively with the basketball for this offense to succeed. Mildly encouraged by the second half, but he's been way off for so long that I'm going to need to see a prolonged stretch of aggressiveness to feel good about the playoffs.
