With the news of Evans possibly being a question mark next season, I can't say I disagree with the ranking.
If Evans is limited or not available that gives Buddy a prime opportunity to step in and be pretty successful. And in comparison, his situation is probably the most advantageous of the guys he will be competing against. Assuming we can stay relatively healthy that is. He will get to be a catch and shoot guy and probably garner the third or fourth most attention given the lineup but have the superior supporting cast outside of maybe Minnesota or Boston(But Brown is RAW).
I would put Dunn right behind him though. But he will likely not start with Rubio still on the roster.
