One guy that isn't spoken on here is Nick Johnson. I tried to gather some intel about him and he intrigues me as a point guard like George Hill. Good shooting, not a consistent playmaker but potentially an elite defender. Good height to defend the tiny point guards in the Western Conference(Russell Westbrook really is the only guy in the West who's taller - but it doesn't matter, he can't shoot so lateral quickness is key to contain him). I think he's really interesting.
The problem with Johnson is he is a SG in a PG's body. He tried to play point guard at Arizona and got moved to SG. He just lacks a passing/setup mentality. Now if he is really that good of a defender in the Pro's he probably still deserves a spot in the league. He just has limited upside.
