Yeah, youngest player ever to get the Art Ross, youngest player since Gretzky to get the Hart, and this week, if I'm not mistaken, Sidney has also been the fastest among active players to get to 300 points by number of games at 219. During the playoffs he tied for Zetterberg for the scoring title -- the youngest playoff scoring leader in modern hockey. (Funny, even then, there was a lot of grumbling from fans about his performance in the playoffs.)
At 21, I don't think there is any argument about whether or not he's on pace to be one of the greatest of all time. I think a lot of people's B.S. is backlash from the NHL pimping the heck out of him as their poster boy. If people look past all the ads and look at what he's done so far, though, he's shaping up to be the real deal.
Either way though, while it's an easy thing to want to analyze where he is and what kind of expectations he might be meeting ...............like Jesse said we should enjoy and appreciate his kind of talent that we have because some day we will miss seeing it.
