So are you suggesting trading everybody except for Petterson/Miller/Demko? Would be a very long road back to competitiveness if you have to find a 1RW, a whole 2nd line, a whole 3rd line, a whole first pairing D, at least 1 2nd pairing D, etc. This would basically be a full tear down rebuild.
IMO its way too early to think about trading Hughes. He is barely in his 20s, plays a position that takes YEARS to refine. He has sky high potential still. Even if you believe his defensive game will never get better, he is still a 60+ points player from the backend, he can still help you win if you give him a competent D partner. What can you get by trading him? Picks/prospects that you hope will one day be an impact player like Hughes? Or lesser NHL players?
I wasn't Boeser's biggest fan the last couple seasons but this year he had been impressive so far. He is a solid 1RW and is worth keeping with Petterson.
We need to keep Horvat as we have absolutely nothing coming up the pipeline on C.
If you end up trading Hughes, Boeser and Horvat, you might as well trade Petterson too because that full tear down is only going to be wasting EP's prime.
You would not be able to "just" trade away all the players.
What I am saying though is having a plan.
Examine the teams in the league.
Some will have issues, fans, play or money.
I like using Buffalo because their problem is a little of everything including playing in a harsh division.
There are players on that team that I covet.
Arizona has money issues and a player or two.
Tampa will have to make a deal due to cap issues.
Maybe StLouis.
At any rate with the exception of Demko and Pettersson I would see what the offers might be.
Putting Horvat in this group is more along the lines of rewarding him for his loyalty in 8 years or more losing, I always felt bad for Nash, a great player stuck on that team, used up his good years.
IMO it is the plan that dictates who gets traded, and not "just" traded for the sake of a trade.
But all the expiring contract deals should be dealt, the team is still in the bottom third of the league.
