I think there will be far too many sellers on the market this year for the likes of Lekhonen to get a 1st (IMO). I mean...unless the Isles go on a miracle run with their games in hand, the Eastern Conference already appears decided...with some teams not even at the halfway mark yet. The 9th place team are the Wings, and they are 8 points behind the 8th place team (Bruins) while having played four more games. The 10th place Jackets are 13 points behind the 8th place Bruins while having played one more game. That means that by the deadline, there will realistically be 8 teams in the Eastern Conference willing to sell. The Western Conference is much tighter, but if there are 10+ teams selling at the deadline...generally only a handful of 1sts are moved near the deadline. And those will be going for the likes of Pavelski, Hertl, Miller, Giroux, Klingberg, etc.
I expect Lekhonen will be in high demand, but for a 2nd or equivalent prospect. This simply won't be a sellers market like last year -- not with so many teams already so clearly out of the playoff hunt.
