Of course Ross has a higher TS%.
Ross:
TS: 53.2%
USG: 18.2%
2Pt %Assisted: 54.0%
3Pt %Assisted: 29.5%
DeRozan
TS: 52.9%
USG%: 29.8
2Pt %Assisted: 25.2%
3Pt %Assisted: 42.4%
Demar carries a significantly higher burden of offense and has a lot less help creating it (at least on the 2 point side of things), it's a lot harder to be efficient in that role than it is in Ross' role. This certainly isn't defending Derozan, but it's not fair to say, Ross had a TS of 53%, so did Carmelo Anthony, therefore Ross is better than Carmelo Anthony offensively, you know what I mean?
