Based on what? He has certainly played better (good) the last 5 or so games, but his season as a whole is nearly identical to last season. Slightly better in some areas, slightly worse in others.
His three point shooting is way down from last. Regular field goal percentage is up a bit, but still low. Rebounding is up a bit. Everything else is pretty similar to last year, including turnovers which are up a bit over last year.
I've been pretty "blah" about his play this year as a whole. I expected a bit more.
