Too much is made of Crosby and Malkin not scoring. Neither one has played poorly this playoffs at all. We simply aren't a well built team for playoff hockey and until that changes, as well as a change in coaching (probably) I can't see us winning. I would love nothing more than to be proven wrong though.
When we won the cup, we had depth, but we've lost Jordan Staal, Maxime Talbot, Petr Sykora, Miroslav Satan, Bill Guerin, Ruslan Fedotenko, Tyler Kennedy, Matt Cooke, Hal Gill, Mark Eaton, Sergei Gonchar, Alex Goligoski.
On their own, most of these losses don't move the needle much, but I really feel that Staal, Talbot and Cooke were significant blows to the this team. Staal and Cooke from a 3rd line, and defensive standpoint. And Talbot for just a locker room presence and support for Fleury. Kunitz was younger, Dupuis wasn't injured.
We are not such a mess than it can't be fixed, we just need the right mixture of players to be put in place.
