I'm not saying he didn't know Bozak and Kadri were there in front of the net; of course he did. But without looking, there was no way for him to know exactly where the defenceman was and exactly how Bozak was arriving at the net. He threw the puck where it needed to go given the position of his teammates, but it's not as impressive as picking out a pass from a skill point of view, in my opinion.
And I watch Gaudreau. I know exactly what you mean about this sort of play. Gaudreau does it too, as do all of the great passers around the league. They know where their teammates are without looking, and know where the puck needs to go, but that doesn't mean that they are in full control when they make a blind pass. They make those passes when they know that the risk on the play isn't serious (like it won't lead to an odd-man rush) and the reward is great (a tap-in or an open shot). And when they work out, it doesn't make it any more skillful a play than the many that don't work out.
I think the best way to explain it is this. If I stand at the free-throw line with my back to the hoop and lob one into the net, that's a very skillful play. I knew exactly where the hoop was and hit it. If a friend moves the net five feet in an unspecified direction, and I hit the shot anyway, it's not as skillful on my part. If I had looked before shooting, it's back to being 100% skill.
