Button had Poehling #4 after the Hlinka two years ago. I wouldn't put much stock into what he says.
I'd say Broberg is more in that late first round range. Very good skater, good size, he's at least an average offensive and defensive player. I'm not convinced he's going to be very good in the offensive or defensive zones. I'd need to watch his game closer, and preferably not only in one tournament. I'm also not convinced about his hockey IQ. And then you have to consider the lack of a track record. I've seen Broberg play before this tournament, but I didn't even remember it because he did nothing that would make one remember him nor has anyone talked about him prior to this event.
