Where did you get your numbers? His TS% and eFG% are both up this year. His 3p% is slightly down but 2pt% is up. His points are slightly down (from 13.6 to 12) mostly because his usage is down. His FT% is technically down from 86% to 85%, very negligible. His rebounding and blocks are up. http://stats.nba.com/player/201583/ Overall he is more efficient this year so far. Still kind of small sample size though.
That strikes me as a bit of a subjective claim, but if you have data to back that up, I'd like to see it. That may very well be the case, although his defensive rating is exactly the same (113), but the home / road split discussion has always been about his offense.
I don't have the data , I've just been at the games . Defensive and offensive rating are OK stats , and this early in the season I wouldn't expect them to tell much .
One Funny Moment in the game for me was . . .. . When they chased Ryno off the three point line. . . and he dove to the basket with the ball the Whole Defense looked so surprised and slightly paniced like "NO ONE SAID HE COULD DO THAT!!!!" Rocket River
