The Malkin/Crosby factor, age (31 when the season starts), and the fact that he probably can't run in all systems makes me think his value probably wouldn't be as high as some people here expect. He'll still get a nice return, but it's not going to be a kings ransom.
Yes, the guy put up 92 points, but 42 were on the PP with Crosby AND Malkin, and he played a large chunk of the season, EV on Malkin's wing. Kessel is a fantastic player, but if you think he's driving the play more than a Malkin or Crosby, you're dreaming. His stats are INFLATED. Think of it like this, and this is a much more exaggerated example, would you pay top dollar for 2005-06 Cheechoo? He put up 50 something goals, 90 something points. No way, cause everyone knows the reason for his success was his center.
