both Dame and CJ have the same defensive rating of 113. Portland's team defensive rating is 110.8, so, both are worse then the team average which matches the eyeball test, IMO
Dame holds opposing PG's to an eFG% of .485 and a PER of 16.4
CJ holds opposing PG's to an eFG% of .491 and a PER of 16.5
and it's worth noting that CJ usually was going against 2nd unit PG's while Dame was facing starters. So, if CJ is
"good to very good" against PG's, so is Dame....and it's kind of hard to buy that
the problems both have is that they are easily re-directed at screens and find it tough to fight thru, and if they do, they don't have the length to compensate for being a step slow in reaction and pursuit.
Numbers often are misleading. Take for instance, Avery Bradley, who is considered one of the best perimeter defenders in the league. All the NBA players (who actually play against these guys) were shocked when Bradley didn't make an all defensive team. When Bradley was on the court, Celts had a net defensive rating of -3.7. Contrast this to CP3, where his team differential rating was +8.8 when he's on the court. Bradley had a -1.72 defensive real +/-. Also Bradley had a "points allowed per possession defender" of 0.922, good for 50th in the NBA. Does that mean Bradley is not a good defender? Bottom line, theres way more to stats than opposing PG's eFG. Its a team scheme, and CJ is in there for longer stretches in the late 1st, early 2nd qtr than Dame + responsible for carrying the offensive load when Dame is out, hence perhaps less focus on D. There are just so many variables, and one of them is the "eye test". I think the majority of Blazers fans would agree that CJ is a bit better than Dame at defense due to his feistiness. That said, I wouldn't consider CJ a "good defender" just average. However CJ at his worst was no where close to Dame at his worst (the Memphis series when we lost with LMA, it was literally one of the worst defensive performances I have ever seen in a series from a star, maybe worse than Harden. Beno Udrich ate him alive).
I know isolated stats can be deceptive; especially defensive stats and perhaps none more then those on/off stats; I think those are pretty tricky. That's why I didn't use them
one set of numbers I do tend to think reflect reality somewhat are those defensive ratings numbers in the context or where a player lands in relation to the team number. Bradley was 0.4 better then his team's rating; Dame and CJ are 2.8 worse. 0,4 doesn't seem like much but Boston's rotation players, with one exception, were all in a group. Boston's rating was 108.4; seven different rotation players were 107 or 108; 3 more were 109. The one exception was Isaiah Thomas at 114, 5.8 worse then his team...

. Anyway, 0'4 doesn't seem like much but when you have such a small variance among rotation players, it is significant
and while Dame and CJ were holding their opponents to an eFG% around .490 and a PER around 16.5, Bradley's opponents had eFG% of .452 and a PER of 11.8. It's also worth noting that Bradley spent a lot of the season injured; he only played in 55 games. I'd guess that had some impact
I'd probably rate CJ a little better on defense then Dame, but not by much. Generally, they both suck. CJ can get by with a little "feistiness" as he tends to encounter more off-ball screens while Dame spends more time being crunched in PnR on ball screens, usually set by starting big men; scrappiness near the ball is going to draw more whistles. Dame also plays against starting level PG's while CJ against starting level SG's and I'd think the eye test would say that the PG position right now is stronger then the SG position. For instance, Portland plays OKC Dame guards Westbrook while CJ draws Oladipo or Roberson; against LAC, Dame takes Paul, CJ takes Redick. Few easy assignments, but NBA PG's are just a lot better at putting opponents on skates. CJ does get his hands on more passes with steals or deflections so maybe he has a little better anticipation then Dame
and of course, what we saw over the last 2 years is that when either Dame or CJ were getting torched by their assignments, Stotts dialed 911 and put Harkless on the torcher. He put Turner on the torchers a little last season but it became apparent quickly that while Turner can do a decent job, sometimes, on larger wings, he gets burned consistently by speed
and finally, Portland's ICE defense did no favors at all for their small backcourt. The bigs heading way back at every on ball screen left Dame and CJ and Napier all on islands at the point of attack. That Udrih example was Dame being run into screen after screen being set by Gasol or Zach, allowing Udrih to round the screen unchallenged, and have a wide open mid-range shooting space because Lopez or Aldridge or Kaman or Meyers were 8 feet away covering the paint on the floor rather than the man with the ball
