I think the only counter to this is that maybe OPJ is James Hardening it this year until he gets with a good team and magically turns into 23-year old OPJ.
Once guys have had serious or repeated injuries, I think they start pacing themselves just to prolong their careers. They pick and choose when to play hard because it's not worth getting injured for a lousy team or a playing situation that doesn't mean anything. I think Blake Griffin is probably and example of this, Jeff Green too.
