Skal is a finesse 4, and guess what, that's fine, won't cost him a dime. He could stop playing college BB after this game and still be a top 3 pick in June '16. That's how much his physicality reallly matters. But in terms of how it effects this team's chances of bringing home #9 is a different story.
In a 3 guard line-up that lacks a complementary bruising PF, Skal's lack of physicality is not only exposed, but it's something that can be exploited.
