STL has no need to trade Parayko, especially for a **** package like that

The Blues need a center and have wanted Kadri for a while, and with his performance in recent years, and his reasonable contract, that's a pretty fair offer. But the Blues aren't going to take that deal. You *might* get them to bite on Nylander. Fact is, while it is true that Blues' fans are notorious for over-rating their players, top-pairing-capable RD defensemen really are in greater demand right now. And, while the Blues are deep on the left, they cannot readily fill in behind Parayko if he's dealt. Carrick is hardly a replacement. And finally, there are other options that won't hurt as bad to acquire. The Blues, reportedly, are still looking to deal for O'Reilly and Skinner--and they won't be trading Parayko to do it. If I'm Doug Armstrong, I move Parayko for no one not named Draisatl. Edmonton won't want to do that, just as you wouldn't want to offer Nylander, or Marner. Sorry, but I don't think he's a realistic target.
I will say, though: that's a scary fantasy team you've assembled there.

There is no way this works. No consideration for the cap after this year. Your whole cap would be wrecked. Mathews alone is probably an 11-12 million cap hit next year. You add Marner on top of it. This is simply not even possible.

The trades really don't help the Leafs, though obviously Tavares does. But Leafs would be carrying over their Performance Bonuses into next year which is cap foolish.

That's pretty much how I'd look at it from the Blues' perspective. There's a very, very short list of players I'd move Parayko for. It wouldn't exactly begin and end with Draisatl -- but Kadri wouldn't be on it, no. Nylander, Barzal, and a few others would be there.
