Here's how. After signing Stamkos the bolts are still fine for cap space this year, but next year, will have to pay Drouin and Hedman, who are both due for about 3mil raises at least. Drouin is coming off his rookie contract, he can expect the quadruple that. Hedman is only making 4mil this year. If they match on Kucherov at 5mil+, they can kiss one of Drouin or Hedman goodbye next year. My bet is that they want to keep the other two over Kucherov, and will be happy to get the 1st and 3rd for him.
If the blues match on Schwartz, they will have about 7 mil to spend in 17-18 on Parayko coming off a rooke contract (3 million raise?), Shattenkirk looking for a couple mil raise, Bortuzzo, Bergland and Steen all looking for raises. If the cap doesn't go up enough, they could be in trouble.
The canucks have to look at what teams will be in trouble next year this time if they sign big contracts now...
only issue is whether the canucks are allowed to sign two players to offer sheets in the same price range... it seems the rules say the compensation is in the next years draft, and signing both of them would mean losing picks in 17 and 18... that could probably be circumvented somehow
