I haven't looked at Haytons stats closely or seen much of him. Soo player as well. I'd be very intrigued by this, but I do worry Hayton isn't nearly as good as his draft pedigree suggests. If you remove the 5th overall draft he was selected at, I'm not sure he'd be considered someone the Leafs would care about.
Coyotes need a lot of things, but a young promising LD to pair with Soderstrom could be really good if/when they finally trade Chychrun. Hayton is from a different management era as well, so they are not likely attached to the player either.
