This is something I wholeheartedly disagree with. I think any team that plucks one of the Oiler's young guns away from them on the cheap is going to get a monster steal.
The way I see it, the reason Hall, RNH, Yak, etc. are considered "toxic" is not because of their individual personalities, but rather because of the situation they have been pushed into. Not even Jesus Toews himself would be able to keep his composure and valiantly lead the team coming into that circus as a young player.
I do believe that once any of those guys are traded and go to an actual NHL team, with real goalies and defenseman and whatnot, they're going to be rejuvenated. Just like Polak said after getting traded from the tanking Leafs, it's nice to play games that actually mean something. I think you put a guy like Hall on the Sharks and give him a chance to play postseason hockey with a few quality veterans and a roster that actual features NHL talent top to bottom, and he's going to flourish. I think they are all simply in an organization-induced funk right now, and that will change with a change of scenery.
If I was DW, I'd target, and target hard, any of Hall, Nugent-Hopkins, Yakupov. I think Nurse and Draisaitl would be huge pickups too, and would probably be my two main choices, but I think they're fresh enough to where Edmonton may hang onto them as part of their second rebuild. The first three I mentioned however, are probably headed out the door as part of the failed rebuild, and I see all three finding a massive second wind elsewhere.
