Given what we have seen over the last two seasons, there are only two players who should be considered "untouchable".
Kooch for his overall play and Vasy as there is no goaltending depth in the system. Both are All World talents, as anyone with an ounce of hockey sense understands.
Players like Heddy and Bagel would need a heck of an offer to be moved as they have proven their worth as well.
I did not consider Stammer as he is a UFA and free to sign where he wants for whatever he wants.
If the team is going to succeed and move forward, changes are obviously necessary, and we are going to have to trade quality that may need a change of scenery to get quality that may need a change of scenery.
As for JBB and Cooper, they should be good for one more season. That being typed, should the 24-25 season go as the previous two have, changes need to be made as you can have all the top talent in the world but if you cannot get them a supporting cast, their talent is wasted.
