He's played 3 games. You make it sound like he's revolutionized the position.
Martinez is what he is. Everyone knows what he is. There are no secrets. If fans don't stay up or care to watch the Kings, that doesn't change value. He scored 2 huge goals a couple weeks apart a few years ago. That's not he scores big goals all the time. He, along with the rest of the team, had an insane run to that Cup. King had a huge conference final once too. He's a role playing defenseman. His value will be the same today, as it was yesterday, and as it will be tomorrow.
By all means though, trade him today if there's a deal to be made. He's got no future here.
It's just speculation obviously, but...
It's 3 games, but it just reinforces that the Kings are excellent at developing defense and goalies, which other GM's already know.
I think you are underestimating his clutchness. Since 13-14 and he became a fixture, he's got more GWG and OT goals than any other Kings defenseman. He has more playoff OTG's than any other defenseman league wide, and is second only to Keith (4) in GWG (he has 3). That's pretty significant if you are gunning for a cup.
Just saying that most GM's don't think logically, and seeing what Muzzin is doing in Toronto as the TDL approaches may get them interested in a guy like Alec more than they normally would be. If you are from the East, 1. He's from the Kings, which had a dominant defense that he was part of, and 2. your competition appears to have improved significantly and you don't have a lot of time to try and catch up. Sending a package is always easier when its to the other conference.
We should definitely take advantage if this is the case.
