Very interesting development. This is how I see the move:
Kyle Dubas probably has 2 want's this upcoming TDL. A top 6 LW'er, and a Top 4 Defensemen. At this point with Muzz on LTIR it could be either an LHD or RHD, but more preferably an RHD.
Given the unexpected and terrible news of Rodion Amirov's health, I am sure Kyle is less inclined to move a top prospect, specifically a LW prospect, as we instantly become very thin in that regard if we were to move either Knies or Robertson. Bunting will be due a major raise in all likelihood in the summer of 2023, and there is a good chance he will not get that raise in Toronto. Leaving the Leafs needing to fill 2 top-6 LW positions in the next 2 years. Who knows at this point if Amirov will ever even play another professional game. So Robertson and Knies should be more than likely off the table IMO.
We also have very little draft capital going forward. Which further complicates our situation, as that is what teams want going the other way in a trade (prospects and picks). Our Prospect pool is good right now, but with the Amirov news and if we were to part with one of Robertson, Knies, or Niemela we instantly become very thin at the top IMO. We have great depth in our prospect pool, but also a ton of question marks associated to most of that depth.
I think Kyle brought Robertson up because he wants to give this kid a run in the top 6. Can Nick be the answer for top 6 LW. We need to see if he can fill that void this year prior to the TDL. We cannot afford to be parting with many more picks and high end prospects at this point IMO, so we will have to try to find answers from within first before we blow our load on a player that may or may not have been needed all along. We have no internal candidates for top 4 RHD, so why not try out Nick to fill our other void in top 6 LW. It could potentially allow whatever capital we were planning on spending to fill that void to be used on boosting a package for a top-4
Defenseman
I think I'd be ok moving Niemela if we were to have to move a top prospect, but it really would not be my preference. The returning player would have to be very good with term left on the deal. I think the one prospect I would be actively shopping is Hirvonen. Not because I don't like him, I see an NHL player there. I just don't think his NHL upside is anything that we'd regret moving. He still has a decent value IMO, and along with say Dermott we could get a good player coming the other way potentially. Especially now that we may not need retention with the Muzz injury.
Minimal loss, but both voids could potentially be filled. Of course this all hinges on Roberston's ability to adapt to the NHL game in the top-6. I just hope they give him a little leash to make some mistakes. Give him a 5 game sample.
