Realistically, how much can this team turn over in one year?
It's probably fair to say the core has failed. I think this mostly comes down to EJ and Varly. EJ is a great defenceman, but he's not the guy to carry a team. Varlamov is too inconsistent. With their draft year already being 10 years ago, if the Avs could move on from them, it would make sense to start a new rebuild. EJ less so than Varlamov, as he will for sure help Zadorov continue to grow, but if there's a chance to get out of the next 7 years, they should probably take it.
Soderberg needs to be the guy exposed to Vegas. He is too soft and one dimensional. Another contract that the Avs should get out of all costs.
I don't like Barrie. I just don't think he does what he is good at consistently enough to overcome the rest of his game. If the Avs are going to swap a core piece for some other team's core piece. He would be my candidate. If the Avs can move EJ and replace him with a younger guy like Trouba, then I'd keep Barrie. One of them should go though.
The three main forwards should be kept, and added to. Avs need another top-6 core player. Preferably large, and strong defensively.
Beauchemin needs to go. Whether that is a trade, a trade with cap retained, or bought out, he can't play in Colorado next year.
Comeau and Martinsen are good for their roles, and should be back next season. Comeau just needs to play a smaller role. McLeod should be shipped out at the deadline if anyone would take him. Mitchell, I'd re-sign if he took a lower cap hit, and keep him strictly for the 4th line.
Grigorenko and Colborne should be offered around the league, if no one wants them, then let Grigorenko walk at the end of the year. Colborne I suppose will have to just come back next season.
The new core needs to be Duchene, MacKinnon, Landeskog, Rantanen, Jost, Zadorov, Bigras. Look for other pieces that are similar age to Zadorov/MacKinnon.
It's sad that you could look at 90 percent of this team and say, "he needs to go."
