From what I can tell from reading Jason Jones blurbs on twitter, and blogs that he's written about the people at summer league, what the kings like about him is he pushes the ball up the court, keeps the tempo high.
The Kings have talked about wanting to do this more, and Tyreke nor Beno does this very often. Tyreke is a great talent, but he brings the ball up lazily a lot of times, which forces you into a Spurs style half court game.....except we aren't he Spurs.
So, they want to increase the tempo and push the ball up the floor....this guy does that.
