No thanks. There's zero need to shove Bortz out, and certainly not for a rental we likely can't extend. This is a lot of work for a small improvement across like 13 minutes a night.

Makes no sense for isles to sell mayfield for Pennies on the dollar

Strongly disagree. How can you argue that the lineup I put together isn't a noticeable improvement over what the Blues would ice if the season started today? And for what, a couple mid-round picks? Depth goes a long way, especially when it will more than likely come down to the Blues or Avs taking the division.

Mikko, a 2nd and two 3rds is not "a couple of mid round picks". And now you've sheared the LD depth down to nothing, while slightly improving depth in places that already had it. I doubt either team accepts anyway, but I'm sure some Blues fans will like what you've done. As for me, I'm not a change for the sake of change guy. I'd rather keep the cohesion in a strict system team unless there's a real upgrade to be had in a place where it's needed.

Trading Mayfield would create a hole at 3rd pairing RHD they don't have anyone to fill atm

Fair enough. However, regarding LD depth, even in my lineup we would have Rosen as a backup LD who was decent when called upon last season. Even Tucker might be able to log some minutes this year.

What are your thoughts on the Stastny signing? Assuming we have the cap space to make it work.

I dont think Blues do it especially at the expense of a 2nd round pick, though I do think both players you traded for are fine. As far as Stastny goes, the Blues got old enough this offseason. They need speed and youth, Stastny is the antithesis to that.
