They should also have a fair number of 2nd liners at forward and some 4th defensemen types in addition to a chance to spend in free agency.
That's a pretty big stretch. Check out this mock expansion draft from last month: http://www.sportsnet.ca/hockey/nhl/mock-expansion-draft-vegas-golden-knights-unprotected-player-lists-nhl/
Anaheim and Minnesota are the only teams in danger of losing an impact player. And if they're smart they'll be making moves prior to the draft to ensure that they don't lose somebody like that for nothing. So it's entirely possible Vegas doesn't draft a single top-6 forward or top-4 defenceman.
Which is fine I guess, I agree that an expansion draft shouldn't guarantee a great team. I just think too many people think this expansion draft is going to really help the team.
