A healthy Rondo would have a huge impact on this team. His ball-handling, court vision and quick decision-making would fill huge voids in the team's current offense.
Currently our guards generate almost no dribble penetration, struggle to run a pick and roll/pop and have exceptionally poor passing ability, court vision and decision making. This forces AB, Jeff Green and Gerald Wallace into primary shot-creating roles on the perimeter - and they are terrible at it. Look at their shooting numbers: 38%, 33% and 41% respectively. Disastrous.
It's also putting pressure on Sullinger and our bigs to shoot 3s, as the guards aren't capable of generating looks for them near the basket or making basic entry passes. Right now Sully, KO and Faverani are a combined 6/30 from deep. Take away those shots and they'd be shooting a healthy 53%.
And a guy like Bass, who depends on guard penetration for his looks, has almost completely disappeared offensively other than a few misguided post-ups and whatever scraps he can get off the boards.
Having Rondo will allow our horde of roleplayers to start playing to more of their strengths. Bradley can go off-ball (he's been our best spot-up shooter, just no one has created for him), Wallace and Green can fill in as secondary slashers, spot-up shooters and post-up players. Bass will be able to get his pick and pop plays. Sully can get a decent post entry pass. High efficiency guys like KO can get more shots and low-efficiency guys like Crawford and Brooks will play less.
