First off, the only time Malkin or Crosby are getting traded are on your PS3 or XBox360. If Shero deals either of them, it would be the absolute height of lunacy, so let's forget about either of them going anywhere. Malkin is on pace for about 140 points this year.
Slightly less ridiculous is notion of trading something significant for Gaborik. Talented player? Absolutely, but the guy makes fine china look durable. I've said before that I wouldn't trade a bag of pucks for Gaborik right now because I at least know I can use the pucks every game. Minnesota has played 279 regular-season games beginning with the 2005-06 season; Gaborik has only played in 196 of those games. He's missed all but six games this year. He's an incredible gamble for a team like the Pens to take, especially when it comes to breaking up their core. If it means dealing a piece of the core like Staal, Whitney, Letang or Goligoski, I want something more of a sure thing.
Nevertheless, it's still too early for any of these teams to make any significant deal. No one is really "out of it" because we're not even at the midpoint yet. No team like Atlanta is going to run up the white flag on their season right now and deal someone like Kovalchuk. A deal like that is still realistically six, maybe eight weeks away.
In the interim, there may be a minor deal to shake things up a little bit, but even something like that maybe a week or two away.
I think Shero does SOMETHING. I even think the Pens are a reasonable candidate for a blockbuster deal at the deadline, but it's going to depend on where they are and where other teams are as well (Atlanta, Florida, Toronto, etc).
