Interesting break-down on Rondo's offense & defense.
Here are Rondo's 5 most-used 5-man units and their defensive ratings (point per possession).
Unit min ORtg DRtg
RR+Bayless+Green+Bass+Humphries 105m .98 1.08
RR+Wallace+Green+Bass+Sullinger 67m 1.00 1.07
RR+Bradley+Green+Humphries+Sullinger 50m .90 .85
RR+Bradley+Green+Bass+Sullinger 49m 1.07 .95
RR+Bayless+Green+Bass+Sullinger 37m .92 1.26
I suspect that the problem on defense isn't Rondo. Or Bradley. Or Green, Hump, Bass or Sully.
Haha. You could spin it as Bradley being a huge plus, though, since the Wallace lineup isn't really any better than the top Bayless lineup.
I didn't mention Wallace in my list of exclusions for a reason. I consider he AND Bayless to be the defensive problem in those lineups.
Wallace is a decent defender at the SF position this year, but he has sucked at the SG spot. Opposing SG's have rated a 16.9 PER and shot a blistering 53.2% eFG against him.
Rondo and Bradley have a prior history in their oft-interrupted-playing-together of stellar, shut-down defense. And the numbers up their suggest they still 'have it'.
Rondo, Bradley & Green all have experience playing team defense together from prior seasons. I suspect they simply know how to work well together. Throw someone else into that mix and it is not surprising that it might not click.
