For all the great passes Rondo makes (and he makes a lot of them), he also detracts from the halfcourt offense by not needing to be guarded by the opposition.
He's leading the league in assists by a decent margin. We score well when he plays and he assists about half the baskets he doesn't make. Obviously people get open on a regular basis when he's playing.
I don't necessarily think he "carried" the team as much as some did last year.
Obviously not. But Cleveland spent the bulk of their series trying to figure out how to slow Rondo down and basically ran out of ideas. Remember LeBron talking about trying to guard Rondo because nobody else on the team could?
He's leading the league in assists more because of his great teammates than his great playmaking abilities. Ray gets himself open, so it's just a matter of finding him at the right time. Not an easy task, but not the only player with that skill-set, especially after 4 seasons of chemistry.
Everyone gets open despite Rondo, who NEVER commands a double-team. They are a great passing team from top to bottom. If he somehow musters up the courage to actually penetrate, again, either they let him put up a contested shot (if our players haven't drawn the defense out) or they simply hack him and make him earn it.
For as easy are Rondo makes it for the everyone with his precise passing, he allows for help defense on everyone. A player who can keep the opposing PG honest would make KG and Pierce's lives a lot easier too.
Unless Rondo has the ball, he is borderline useless. That's not true of anyone else, even Perk for his screens. Ray, KG, Pierce all need to kept close because give them too much room and they will burn you.
I never take much stock in LeBron's words of wisdom. IIRC, didn't he defend him and do a semi-decent job?
