As long as it's not Larkin, DeKeyser or Mrazek, I'd probably trade anyone for Trouba. Smith+ Svech/Mantha/Nyquist/Tatar/Shehan/1st+ Pulks/Jurco
Thats a lot of "nice" pieces but nothing great that Chevy will probably be enamored with.
Pulkkinen/Jurco probably struggle to crack the lineup in WPG with all the prospects they have fighting for spots.
Smith is meh, but no where close to replacing Trouba on the back end so they already take a significant step back on the blue line.
Svech is a complete unknown on how he pans out and likely too far away from NHL action to interest Chevy
Mantha is a nice piece and has shown some flashes on the NHL level, but still far from a sure thing. Opinions seem to sway on what he will be on the NHL level
Nyquist IMO disappears too much and with his salary at $4.75 mil per, that might be too rich for what he brings, especially if paired with Smith, thats $7.5 mil in salary WPG is taking in return. THey might as well just throw $7 per at Trouba which Im sure he would take and run to the bank with
Sheahan is a nice bottom 6 player, but I dont think he helps get a deal done unless he is a 4th piece of a large package
Tatar is a nice add, but he is an upcoming RFA after this year likely getting a big raise, so it would be the same situation as Nyquist. If paired with Smith, the money going back to WPG is just too much, especially since they are a budget conscious team that wont spent to the ceiling
Theres a lot of quantity options here, but not as much quality going back IMO
I dont think you want to trade an A rated player for several C+/B- players
