Martone needs to work on his skating, that's no secret. Also no secret Michkov came to camp out of shape after not stepping on the ice all off-season. He said it himself. And then he worked his butt off during the Olympic break.
Nobody is getting a pass. Martone was skating and yes, working out with an NCAA team all season. Not being as fast or as good a skater as he could be is not the same thing as flunking your cardio tests (which is something the team leaked during the controversy, not a great moment for them, but also still probably true).
I dunno why you think he's gone, by whose choice? He has no leverage (under contract next year, controlled a lot longer than that). The team won't trade him in anything other than a blockbuster deal. And I don't think he's going to get caught in a logjam, he's still one of their most important parts of the future.
And who cares what the ESPN announcers say.
