What's the specific argument that BKerr's making here, anyway?
Is it:
A) If Ryan Johansen is traded, the Blue Jackets will likely not get an player/prospect back with the value of Alex Galchenyuk
Or is it:
B) The Habs could potentially convince Columbus to trade them Johansen without giving up Alex Galchenyuk
If it's argument "A", I'd say he's probably right. I do think that Johansen is a higher value player than Kerr's oft-cited examples, Evander Kane and Ryan O'Reilly. Both because of Johansen's contract/rights status, and because Kane and O'Reilly weren't 6'3", 225lb centers coming off back-to-back seasons of around 30 goals and 70 points. But whether it's Evander Kane, Ryan O'Reilly or Tyler Seguin, impact players are pretty much always traded for a collection of lesser assets these days.
If it's argument "B", that's where he loses me. Outside of Galchenyuk, I don't see any expendable assets in Montreal's possession that are as compelling as any of Tyler Myers, Nikita Zadorov or even Mikhail Grigorenko.
