Moving our top 6 forwards won't help either. Don't get me wrong, we need some top 4 defensemen as well, but if we trade our top 6 forwards to get them we're just shuffling deck chairs. Nuge isn't the guy to move anyway, he's a valuable part of the success of the team.
If we are upgrading our RD, we need to move a RD out, as we already have 3 NHL caliber RD. Some St. Louis fans have said that they need Broberg or Bouchard if we are making a move for Parkayko, but I think Bouchard has more value at this point. Broberg is still a question mark, and its apparent that Holland isn't going to trade him unless he crashes and burns, and then he won't have any value anyway. Parayko might be too difficult to sort a deal out for, but if there was a way to include Barrie as part of the package (yes, I realize you're going to say he has negative value) along with some futures to even out the value, then something between Edmonton and St. Louis might actually be able to happen.
That said, I can't see St. Louis selling until the deadline. Not now. They were in worse shape at this time of the year the season they won the cup after all.
