RNH, Huberdeau, Landeskog, Larsson and Strome gone in top 5. That's the scenario they don't like.
Most likely this. If this happens they probably take Zbad. We know they don't like Couturier and if they trade down they run the risk of missing out on Zbad later and settling for a defenseman like Murphy.
I don't see couturier as a bad thing at all. In fact I'll agree with Rooverick, that would be great. I'm thinking the scenario they didn't like was huberdeau or zibanejad left. Personally I'd be happy with any of those guys. I just beleive that Strome or Couturier are the guys the sens want to be at 6 (realistically, although you never know)
Adding Larsson would allow the Senators to trade some of the their D prospects to team that really need some. It would be a long process, because ideally you'd deal those at next year's draft, but it's still a good scenario considering Larsson is going to be great according to everyone.
Lets speculate for a moment that Larsson falls to #6 and the Sens take him. Most are saying that the Sens can now trade from an area of Depth, but WHO do you trade? The big 4 that have the most value are:
Cowen, Rundblad, Karlsson and Larsson.
The other in the org aren't going to get you much in return so lets ignore them, so again, which of those 4 are you ready to give up on, considering we've only seen one of them play!
