I have an idea. Lets be rational for a second. The Isles are going nowhere with their forwards, D, & Gs. Even if you got Erik Karlsson it would be a marginal upgrade for a team that wouldn't be able to get out of the first round if he willed them there. Even worse, you'd be ****ing up the salary cap for years ahead by signing him. Just wait a year. Tank in 18-19 and take the lottery pick in 2019. You probably then have Toews, Dobson, and perhaps Aho ready to enter full-time. We see what is happening with Soderstrom and Sorokin. Don't go for the quick fix and ultimate failure.
Tavares hamstrung this team in every way this season, through the draft, and the UFA period. Don't compound this by making a second huge mistake (the first one being JT wasn't asked to sign by trade deadline).
