Thinking about this more and the only way we move Tierney is if he is asking too much or we sign Tavares. With that said I'd like to package Braun, Tierney, and Boedker for an upgrade at RD.
Meier-Tavares-Labanc
Couture-Hertl-Donskoi
Kane-Thornton-Pavelski
Sorenson-Goodrow-Balcers
Vlasic-RHD
Ryan-Burns
Dillon-Heed
Jones
Dell
D that I would be interested in are (not saying value is fair just people that I want)
Alec Martinez (probably won't happen since he's a King)
Connor Murphy (haven't really decided on this, I think I would want more)
Matt Dumba (probably way too valuable)
Jared Spurgeron (again probably way too valuable)
Ryan Ellis (doubt Nashville trades him, and probably too valuable)
Matt Niskanen (this one I could see working if Capitals resign Carlson)
Charlie McAvoy (one can hope right?)
Aaron Ekblad (way too valuable)
Josh Manson (he's a Duck so probably won't happen)
Brandon Montour (again Duck)
Adam Larsson (too important to Oilers I would think)
David Schlemko (buy low, last resort option)
Dougie Hamilton (too valuable, but would be ideal)
Jordan Schmaltz (could be another option that wouldn't cost as much)
Markus Nutivaara (just resigned him but probably not available)
Erik Karlsson (obviously)
Mike Green (another buy low, just costing cap space)
Stephen Johns (buy low option)
Julius Honka (probably not available)
Damon Severson (probably too important to Devils)
Tyler Myers (would need adds to even out value but not sure if Jets want to sell)
Tyson Barrie (another ideal player that is too important to his team)
Jason Demers (would need to send salary back)
Niklas Hjalmarsson (don't know if Coyotes want to sell him)
Kevin Shattenkirk (would need to send salary back and waive NTC)
Ryan Pulock (doubt NYI want to give him up)
Players that probably could be had
Murphy, Niskanen, Schlemko, Hamilton, Schmaltz, Karlsson, Severson, Demers, Hjalmarsson, Shattenkirk
Any of these players I'd love to get but it's just a matter of finding the right deal because the Sharks don't have many pieces that they could move.
