Put me in the "suprised to see if he goes this quickly" camp.
While there's obviously a number of teams looking to add in the middle, and Laughton screams "this is the type of guy you need to win in the playoffs", I get the sense that there's a number of centres available that are either better than him, or viewed similarly.
He's probably not the "#1 target" on any team's trade board... so you kind of have to wait to see how the deadline begins to shake out, and what happens with some of the bubble teams like the Islanders.
Of the top of my head... Brock Nelson, Trent Fredeiric, Charlie Coyle, Ryan Strome, Ryan O'Reilly, Yanni Gourde, maybe Brayden Schenn; all potentially avaialble to also play a role similar to what Laughton would.
