Agree, and what makes the Hawks so dangerous is they have so many options, Bickell (at least in the playoffs), Sharp, Hossa, Saad (who is really coming into his own), and more younger players on the way. They play the cap game very well, look at what Bolland signed for, while be is still a solid payer, no way the Hawks should have kept him.
You can say the same of the Kings, I think the days of building via FA are over at least for the long term, you might get a good year here or there, but unless you can replace the bottom 6 forwards and bottom 2 D-men with young/cheap talent and have them occasionally become top 6/2 players, there is no path to sustained success in the NHL. Add that when you are good, guys like Richards will sign on at a lower price/shorter terms for a chance to win the Cup
Bowman has been a genius at this, he went all in for the first Cup, then quickly shifted gears for the long haul .. which you can do when you have guys like Toews and Kane at the core of the team
