Two big differences with Fox this year is he's far more patient when he's going into the paint and his shot is better at all 3 levels. I mentioned this after one of the first games of the season, but he's just not barreling into the rim protection all the time, but changing speeds, changing angles, pulling from different spots in the mid-range. It's helped keep defenders off-balance which I think has really helped him put up elite efficiency. It's a lot like what Steve Nash/CP3 used to do all the time where they're probing the defense and just waiting for the right moment to dish or put up a shot.
And just at all levels, his shot is significantly better:
At the rim: 90% eFG !!! on 31 attempts
3-10 feet: 57% eFG on 49 attempts
10-16 feet: 63% eFG on 27 attempts
3pt%: 36.5% on 52 attempts
Last season:
At the rim: 71.4% eFG on 217 attempts
3-10 feet: 46.6% eFG on 292 attempts
10-16 feet: 45.1% eFG on 206 attempts
3pt: 29.7% on 249 eFG attempts
