The thing that jumps out at me is how different (and jarringly disconnected) the game looks from the players eyes than it does from our seats or television. It's amazing how they can see and execute what they see and do at speed, while being hit constantly by opponents. Anyone who's played the game knows the feeling, but these guys are operating at such a different level of speed and contact than beer league hockey....
That said, its interesting to see how the game looks from the ice. For my level of play its all much slower, but this gives you more of an appreciation for the talent level
Certainly the talent level enables the execution, but baked into talent is also the instinct and decision-making aspects. I guess when you practice and play as much as these guys do, seeing the opportunities and having enough talent to make something out of them at full speed is what makes them NHLers.
