Holl for a 5th is reasonable. The other 2 are not at all likely. Also Klingberg at that salary is probably not happening. When you think about it, why would any team trade for Muzzin unless they get some nice compensation if they could Klingberg for a cheaper price.

Crouse can be re-signed for term, or traded for long-term assets. Kerfoot is a rental.

The entire Los Angeles fanbase and the knowledgeable, unbiased part of the Toronto fanbase have explained hundreds of times why Muzzin to Los Angeles doesn't work, although technically, a Sean Walker for Muzzin with 50% retention exchange can be fit into the Kings' financial structure. Walker is the only defenseman Los Angeles would be likely to send in a Muzzin trade.

I would imagine Kerfoot has Arizona on his no-trade list and probably zero chance that he waives for them. Oilers didn't move Barrie, so no need for Holl. I think Dubas could move Holl easily once defenders start moving around and teams move cap compliance. Trading Muzzin is probably not something they want to do but if they do end up trading him they probably would need to take back a similar contract or at least a 3m+ contract and will likely be for a RD. Not sure why people are so high on Crouse, when he has nothing to show for it. Sure, he had 20G but someone has to score. That top spot will be available to Robertson and others to battle for, and if none work out, expect the Leafs to make an in season acquisition (I'm sure they will kick tires on Patrick Kane at some point if they haven't already).

There has been talk about Klingberg taking a short term deal on a discount, I'm guessing it would be something in the 6s, although I think he wants a long-term deal but the teams that are offering that to him atm are probably not places that he would like to play in.
