Doroeyev is too valuable of a player to Vegas. He's their best shoot first guy. The only way they trade him is if they can't afford him anymore or if they believe Brett Howden or Bowman can fill his shoes. Howden is great in the playoffs as we all saw this year but he's yet to show consistency in the regular season.
They could offer Hertl to Detroit if Vegas need more cap space. And picks on top, maybe a guy like Bowman. He looked really good in his time this year in the regular season, should be a regular next season
