So basically, what you are saying is...
Malkin, Crosby, Gonchar, Staal, Fleury ... Ovechkin, Semin, Backstrom, Green ... you only need a handful of the seriously top end guys to compete every year.
QFT, you've hit the nail on the head. Couldn't say it any better than that.
Look at the penguins and you see how it can be done. Not pulling a homer, because I would say even the red wings had the same and you'll find mos champs have the same thing in common. A few top stars and then depth depth depth.
I'll look at the pens since they are easy. Start with the 3rd line. You got Staal who is a stud, backed up with Kennedy and Cooke/Talbot. The last three are by no means top 6 players, but they have amazing chemistry that they could be a top 6 line. Wait, what does the hawks want to do? Break up the team chemistry for superstar player?
Then you got the malkin line and crosby line with some formation of Dupis, Guerin, Kunitz, Fedotenko, and a few other cast members. Again, a lot of these guys are third liners on most teams, save maybe Guerin. Again chemistry is why they work. It was the big thing in Pittsburgh to find someone Crosby could play with and be a machine. They tried Hossa and he bailed, so another superstar was not the answer. Instead they have more depth players.
Then on the back end, Gonchar leads the group followed I would say by Letang and Orpik. But then you still got quality dmen in McKee and Gololski (lol). Throw Fluery in net who is a top goalie in the NHL (when he isn't hurt) and there you go.
It is why teams like the Hawks are good now, because they have a lot of young depth. The issue is, you need to keep that depth. Same with the Kings, they are turning into it, and the Leafs HOPE to turn into that. Because honestly, superstars hardly ever win championships on their own. In terms of Washington, that is what happened last season. Ovey couldn't do it all himself and finally the tank ran empty.
Hawks honestly IMO screwed themself on the Hossa signing. Hossa hasn't won a cup yet and has choked on how may teams now in the finals? Why would you not spend that money on solid depth guys.
