They're going to ask for Galchenyuk in return which is why this trade is never going to happen.
Well I agree, that would be idiotic for Montreal to do. However, there are always other options. Yzerman is clearly goign to ask for Chuck though, he's clearly the better player and like 2 years ahead in his development.
This trade for Montreal would be best case scenario a sideways move. And that would take 3-4 years to even be able to see. Tampa would have to add something significant imo to make up for the development disparity. Not sure what, a 1st round pick maybe?
