Since when? There are plenty of teams with three or more players of those three's caliber.
Okay add in what Valimaki will cost, Andersson, and one of Brodie and/or Hamonic... Other than the depth the only area Calgary has really big promise is on the back end.
Valimaki is likely the defensive version of Pettersson in Vancouver. Should we jeopardize the teams defense to keep one player?
Pitt has Crosby (Discount contract), Malkin, and Kessel (subsidized by the Leafs). Washington has Holtby (Discounted Contract), Carlson, Ovie(Discounted Contract) and Kuznetsov (Discounted contract).
Now who else has won a cup in the last decade?
Chicago, LA, and Boston.
Toews, Kane, Keith, Crawford and Seabrook account for almost half the payroll and they are not likely to compete again while Toews and Kane are under contract on Chicago. FYI they won their cups with Toews and Kane making 6.5 per.
LA has Doughty, and Kopitar taking up 25% of their cap and are not going to be competitive.
Boston had to retool because of contracts that were unsustainable.
There may be teams with that situation but repeat Cup contenders have 1 thing in common trade or chose not to re-sign your assets that will cost you.
Chicago- Sharp, Versteeg, Ladd, Byfuglien, Saad and Panarin. They only screwed themselves when they re-signed Toews and Kane for huge money.
Boston-Seguin, Boychuck, Horton, Lucic, and Hamilton. Chia did them in by trading away some of the wrong players.
LA- Screwed themselves with Mike Richards and when Kopitar and others needed new contracts the free agent market was not an option.
Pittsburgh- Sheary, Fleury, Rust, Perron, Cullen, Tom Kuhnhackl, Trevor Daley, and Chris Kunitz.
