How does not winning a Stanley Cup not make a player a superstar? Is Stamkos, who hasn't even been to the cup final, not a superstar? How about Ovechkin before the olympics? How about the many of stars that have been on teams that couldn't get past that final hump due to any number of situational things that can go wrong during a playoff series, no matter how good you are.
No, serious conversation.
Also the Sedins would destroy in the east as they have already demonstrated by scoring a huge amount of goals out there. Henrik Sedin was scoring at 1.89PPG rate (one of the highest PPG rates seen in a long time) against the East (vs 1.28PPG rate against the West) in his Art Ross year. Just a quick glance at game log from last couple of years and it looks like a 1.4PPG+ clip against the East. As I have said plenty of times (and proven with stats), it's easier to score in the East.
If you're going to come back at me, come at me with facts.
