If Corrado has gotten 1 game in 36 and is now on a 2 week conditioning stint you can be pretty sure the team doesn't plan on him getting anywhere near 30 more games, so you can probably see that as a hint to what their plans are regarding expansion requirements for defenseman at least and it's Marincin.
I edited this to my last post but you quoted it too quickly, but he's not going to get the required games, and Vegas isn't going to take him, so despite being exposed anyway Corrado is basically as irrelevant as Lupul is to expansion at that point and nobody would ever claim that we're holding onto Lupul for expansion.
does Lupul even qualify as one of the exposed players? Don't the players a team has to expose have to be healthy? I know you can expose an injured guy but thought they would have been extra on top of what a team had to expose.
