Vegas may get a better deal from another team for a player on a non protected list then the team they are picking from. I heard they're up to 3 1sts in the coming draft so far.
There's some good names on the unprotected list for the expansion draft. https://www.nhl.com/news/protected-list-for-vegas-golden-knights-nhl-expansion-draft/c-289972722
I'll probably regret trading away pitching depth, but adding Schwarber to my young offensive core was too good to turn down. He'll lose a bit of value if he loses C eligibility, but with Sanchez at C already it won't hurt me too much.
