One aspect of trading EP for a young up and coming potential super star that might encourage a team to take that chance.
TIME.
Winning isn't done with "hope". Winning isn't done with "potential".
Winning isn't done with games, goals or success not yet played.
Time is chaos, it changes structure, erodes skills and adds expenses in a limited environment.
Any trade for EP involving a young stud or two is a trade for time. That time being now and the immediate years while he is in his prime. His position will be locked up so the need for a replacement can then take years to accomplish. Make the GM job much easier.
Then there is the attraction of other FAs to come and play in that market.
For EP it is where are the Canucks in 4 years? Other teams can answer that as far as the foundational players not counting him.
Fantalli in a trade? Not as big a gamble for Columbus as some might want to believe. They have many young players playing in the NHL.
IMO I would love to see Voronkov, Marchenko, Jireck and Fantalli in a trade for Pettersson. Columbus would still have Sillinger, Johnson, Chinakhov, all their draft picks and other under 20 yr old prospects. They might even get Celebini or another top 3 pick.
Could simply be Elias wanting to bet on himself and sign a 3-4 year contract to maximize his earnings and the Canucks taking it as he doesn't want to be in Vancouver long-term.
It isn't about money, for years, 4 to 5 at least, he has said it is about winning. Publicly. Well documented.
I think Davidson, for his legacy, will offer sheet Pettersson, a one/two year offer of 15 million which the Canucks cannot match without destroying the team. An offer sheet with the entire roster kept intact would be very enticing for Pettersson.
Ditto Buffalo.
Columbus and Buffalo could be the front runners but once word is out there could be more. The more offer sheet potential the less leverage the Canucks have.
