Tavares, Hamonic, and Nielsen. Can't replace the top-end scoring and center in Tavares, cannot trade the most defensively sound and big defenseman in Hamonic, and cannot replace Nielsen's ability to hold a line together (secondary scoring lives and dies with Nielsen's line), his defensive responsibility, and for a team as low on wins as the Islanders it probably isn't a good idea to trade the shoot-out king when you need every win you can get.
Everyone else is expendable, and Nielsen would be too if not for a total lack of centers on the team.
This is silly...for the right price, anyone could be had.
Perhaps it would make more sense if this thread were titled 'the players your team that are the least likely to be traded', because I'm fairly certain that most of these lists are treating it that way.
I truly see John Tavares as close to untouchable as anybody else in th league, at least under Garth Snow. I know he still hasn't hit the PPG mark yet but his loyalty and dedication to the organization makes him that much more valued to the Isladers.
I dislike seeing lists with half of a team on them, so:
Untouchable (In order)
Burns and Vlasic are my only true untouchables. Burns is the young, all-around #1D we desperately needed with Boyle declining. Vlasic is the type of player that is worth a million times more to the team who has him than he'd fetch in a trade.
Thornton and Marleau will probably not be traded as they have roots in SJ (wives, kids, etc) and NMCs. The only way I trade Thornton or Pavelski is if either they request a trade, they intimate that they aren't interested in re-signing in SJ after their contracts are up in Summer 2014 (I have a weird feeling Pavs won't, hope I'm wrong), or we have a chance to send them to a contender for a great futures package. Marleau, I'd trade if we got a really good return, but honestly, I don't think he'd ever waive his NMC. Couture I'd only trade if we were getting a better young forward than Couture in return. I'd be very hesitant to move Demers because I believe his upside is through the roof and he wouldn't get good value after the season he just had.
Boyle has been supplanted by Burns, I'd trade him for reasonable return. I'd trade Clowe for a younger 2nd line forward or a really good top-6 prospect. I don't think Havlat will be moved because he's a great fit and not in high demand, but I wouldn't be opposed to moving him. Murray should be gone for picks. Stuart won't waive. Niemi might be gone when Alex Stalock is ready, which could be as soon as next year.
As for prospects, there's no untouchables, but you'd be hard pressed to get me to move Tomas Hertl. I love watching him play and I'm really high on Hertl, as I'm sure SJ management is. Anyone else is potentially available.
