I don't think there is anything individually happening with any of these players, where they are lazy, not committed, bad personalities, etc. They have been in a negative situation for so long, and it is going to take some very thoughtful and deliberate moves to get the team over that hump and re-tool.
I think it might be a case where they need to rebuild the room with some tough veterans, who have won before. They may have to shake up the roster and re-tool, because this is clearly not working. They will move out 2-4 name members of the team, and go out in the summer and acquire their replacements with those assets.
Remember, the current management group didn't construct this team. They have no attachment to the players. It isn't like Staios is taking over a proven winner and just needs to add a few finishing touches to get them over the finish line. He is taking over another manager's vision, which has been a proven failure thus far, despite the rebuild supposedly ending in 2021.
These are predictions, not hopes, but I could see Chychrun and Batherson being the two big names moved at the TDL. Maybe Joseph, who has been excellent, but could be justified as selling high on. Those would be the easiest players to move who at this point might return major assets at the trade deadline. Assets which can be used to acquire players in the summer to retool the team in the image of the new management group.
In terms of free agents, Tarasenko, Brannstrom, and Kubalik all will be either traded or walked away from.
Then in the summer, they use those assets/cap to bring in bigger and tougher players and hopefully a cornerstone top 4 RHD. Both of which is easier said than done. They will have a turnover where they have roughly the same core of Tkachuk, Norris, Stutzle, Sanderson, Chabot, etc - but there is a big enough shakeup where 6-10 roster spots are completely changed.
