Locke needs to normalize his numbers across multiple seasons. Saying x percentile of a season and comparing it to past seasons is it another way to make numbers lie.
The problem is that he's using synergy percentile, which is just based on PPP. A higher percentile doesn't necessarily mean a better isolation or transition player. It's kind of like basing your evaluation of shooting solely on 3FG%. If you don't consider context/volume, you would come away with awful takes on 3 point shooting. For example, Cody Williams shot a higher percentage than Tre Johnson from three.
