Our first round pick for the next few years is a blockbuster asset. And all the good young players we don't want to trade like Bert and Hronek.
Considering this team will be in the basement for the next year or two at least, Detroit's first rounders are great assets. They have other good pieces too, as you know: Zadina, Cholowski, Mantha, Hronek, Bertuzzi, Valeno, etc. Gotta give to get.
Boy I'd hate the thought of giving up a 1st to get a 30 yr old Subban, only for our basement 1st rounder to win a lottery spot. If we're going to be in the basement for 2-3 more years, I'm not giving up picks with high odds at winning the lotto. I would have given 6th OA for Trouba but that is already known to be outside of the top 5 so there's a better idea of the value you're giving up. You can say they'd be traded with lottery protection but then that removes a great deal of the blockbuster incentive for the team acquiring the pick, negating the whole point.
I don't consider Bertuzzi, Cholowski, or Veleno (never mind the 'etc') to be blockbuster level players. Maybe Mantha and AA outside of Larkin but that's really the extent. But if we're really prepared to sacrifice assets of that significance, guys who we project to be a major part of the future, then why not just beat 20th 0A + Pionk now? The whole concept of a 'blockbuster' implies that that price would be a great deal more.
At some point you have to just bite the bullet and take a step back if you think it'll allow you to eventually take two steps forward. Anytime one of these 'blockbuster' opportunities arises, we're gonna see the same chorus of naysayers who are full of reasons why it's a mistake but an empty well when it comes to alternatives. We just missed a huge opportunity, who knows when the next one will be. And odds are it'll be much more costly.
