So we should look into your crystal ball instead?
Yes, if you truly think that Blue Jackets challenging for Stanley Cup this season was anything but a false dream this year. In that case two draft picks for Gaborik (that Columbus couldn't likely been able to defend in free market competition if they somehow could have justified even offering something reasonable for him based on his play and role played) contribute more towards building, not buying or selling that vision of future shown in my crystal ball.
In my mind it is just honest truth that this team with or without Gaborik doesn't have for example Los Angeles Kings kind of arsenal in their use. There ain't (yet) star players of Kopitar or Dougthy class, Bobrovski still has some questions regarding his pressure control and the process for building that core has merely began. Coaching staff has come up with two strong seasons of almost overachieving which is a positive signal. Same can be said about fair chances given to younger players and the organization behind team.
If Richards and his staff can be that difference maker it might make the road shorter but if this was a great season... Nice team identity and all in place now but it just usually takes quality to win. Even in the optimal case it takes seasons to gather that.
The only team anywhere near that same level to make even Stanley Cup finals (not winning it) this decade is New Jersey Devils (and they boasted some offensive names in Kovaltshuk, Parise and Elias) and I guess that speaks little towards why the winners for that period are Boston, Chicago and Los Angeles and not Florida, Ottawa or Buffalo out of the teams that made play-offs.
Would Dallas Stars have became more succesful with Gaborik added on prior play-offs? We don't know but honestly I think we know.
