Note that I never said Boissard was 'good' for his TSP level because he isn't. I just wanted to point out that he has things going for him, especially the 17 JR which is rare to see on guards much less SF's (14 ID clearly isn't enough but it's still his best position overall). With the change to outside shooting back in season 52, that level of JR can pierce through even the best defenders.
You might argue that I'm wrong on this, but consider that his PPG in last season's B3 was 28.2, with a 3PT% of 37.1. His league numbers are also impressive; 27.7 PPG both this season and last in Ukraine Superleague. And when he has gotten an extended run for France this season he's typically gone off for a lot of points. The numbers don't lie, and they say that playing against Boissard is all about outscoring him, not guarding him.
