I disagree somewhat with @quinnjj -- I think that Hughes, Hischier and a first gets you Dahlin, but certainly not Eichel. But the OP is absolutely right -- this idea calls into question the credibility of the originator (Lawton, not LeafsFan4Ever34).

So three first overalls?

I'm basing my comment on the report that Kevyn Adams said he was looking for four first-round-pick values for Eichel, hence I was disagreeing with quinnjj's implication that Hischier, Hughes and NJ's 2021 first would get the Devils Eichel. Personally, I think that such a package SHOULD get Eichel because each of those firsts is more than a standard first-round-pick value. But no Buffalo fan on this site would accept that package for him. And I think that Dahlin's value is substantially less, too -- but again, I was trying not to antagonize the Sabres faithful, who believe that Dahlin = next Nick Lidstrom.
