What makes a superstar "Super" in hockey?

I'm just wondering what others think. It's really not that they're much better than everyone else. They may be faster, have better puck control and shots, may p better, but it's not that noticeable a difference most of the time. What seperated Pronger who's only real advantage was size and a big shot from the other defensemen with size and a big shot (Such as Adrian Acoin), or what seperates Paul Statsny who, although he's a smooth skater and has better than average hands, what seperates him from the other smooth skaters with good hands (Such as Nikolai Kulemin) in the NHL?
