As bad as Durant was he still outperformed DeRozan. And Durant is getting crushed for how poorly he played while no one has even paid attention to DeRozan. They are just in a different class of player
Durant - 26.3 ppg, 5.8 rpg, 6.3 apg
DeRozan - 20.8 ppg, 5.4 rpg, 4.8 apg
DeRozan did shoot better from the field, but was 0-9 from 3 and shot less FT's while playing 1 extra game so Durant's TS% was 52.6 to 48.1 for DeRozan. Durant had a higher GmSc as well.
Durant was awful, but he was better than DeRozan. That is how bad DeRozan was.
And for the record, this is why I never believed in Chicago and pretty clearly said they weren't any good. Lonzo Ball wasn't going to save them either. They just don't have a top tier talent, and you need those guys when the going gets tough.
