So this is confusing.
On the one hand, it makes sense to me because I have been saying that I don't think the Spurs would take Dillingham because he's a defensive liability. So trading him for an unprotected 1st rounder is a great return in my opinion.
But...
The Spurs need shooters. And Castle is not yet a good shooter. So they must have serious doubts about how Knecht, Buzelis and Carter could be at the NBA level.
Pretty shocking stuff here.
