Gotcha, thanks.Like I said I don't have a firm opinion. My one thing that has stuck to me is that ever since that injury, he's not the ironman he used to be, especially during his LA year when he was dragged to the game even though he wasn't himself.
Looking at this basketball reference page, I see that his FT% has dropped from the 60s during the first part of his career to the 50s after that. Also, most advanced stats like PER, WS, BPM show a dropoff from his peak in Orlando. Last but not least, his shooting less might be a result of him getting less touches -which is pretty likely a factor thanks to Harden but also it could be because he can't create the same type of shots he used to be able to create.
And sure, as a big man who's turned 30 I would say that his numbers falling from his mid-20s peak is perfectly understandable. But him shooting less (while still hitting a good percentage) shows that he understands that his game has changed. If he still wants to get paid like he's 25 and completely healthy then no thanks, but the guy can still play and his rate stats have been pretty damn consistent.
