Random thoughts:
Hartnell's contract appeared to be too long to get any interest in what looks to be stagnant cap scenario. But other than term, his cap hit and actual salary are pretty good deals in comparison to his production. If he's producing, the only 2 reasons to trade him are a) concern he will decline; 2) clearing cap space.
There aren't any takers right now because of #2 - the teams chasing the SC don't have cap space RIGHT NOW to do the deal and keep their core that is the reason they are in the hunt; and CBJ is simply in a position that it must refuse to take contracts back. That might change this summer - and if so, then we see what we can get. If no change, Hartnell is not a bad player to keep (minus penalties) IF he keeps going at similar production.
Tyutin - not a pickup anyone else apparently wanted. Simply not good enough to provide enough help past rental for playoffs; and he is not a rental - his marked loss of speed/agility make the additional years on his contract problematic. He would be the classic rental otherwise. We might still be stuck with him even after the summer (hope not); if still untradeable after the summer, then if ever there was a buyout option, he would be it. Admittedly he's been playing a bit better, but not worth anything close to his contract as limited 3rd pair D.
Boll - One more year. There won't be takers. Buyout wouldn't save much. If the difference is all they need to get room for Jones/Jenner contracts, then they will do it, but thinking that additional space created by a Boll buyout won't be enough when added - it will take more space than that, unless they are bridging Jones and Jenner.
Cam - A keeper on a good contract. Not sure why some are fearful of losing him, as I see and hear nothing that suggests he is trade bait. The good contract may make him attractive to other teams, but it is also why he is attractive for us to KEEP!
Bourque frees up $3.3M. Tyutin buyout would free up $x (something less than $4.5 i if we can't trade him). C-Mac waived, maybe picked up, maybe LEM. Campbell needs to go some way to free up some space. That would be enough to get Jones and Jenner signed on bridges. I'd like to see Jones on a long-term, and if that is the FO goal, then they will find other moves to create space, be it Hartnell (with something retained), Foligno, Bob, even Dubi, etc...; how they end up in the draft will drive who/what/when. A top 3 winger would make things interesting. Winning the lottery entirely (sorry Jarmo, CBJ is NOT making the playoffs), would really make things interesting as far as getting Matthews and opening up other options. I'm not suggesting that they should dump any of those vets, I'd frankly prefer to keep most/all, but the balancing act will not be easy to achieve appropriate space and also keep enough veteran presence to be a playoff contender in the short run. There are almost no untouchables - maybe Jones, Murray, Saad, Jenner (because of contract low hit if bridged)...
