I could seriously see Vegas taking a chance on Domi. Their third line is currently formed of Cousins - Roy - Tuch. Roy and Tuch are super fine, but Domi would certainly be an upgrade over Cousins. Roy can also be used on fourth with Carrier and Reaves, and Domi used at C. Paul Stastny is currently the second line C, but that could change next season. If the possibilities for second line C are Glass, Stastny and Domi, while having Krebs in the system, you definitely have depth.
In return, I could see Hague coming back (huge LD), maybe even Nicolas Roy, this year or next first or one of 2021 2nd rd pick. Pavel Dorofeyev is also an interesting prospect.
