Not all players need to meet those requirements! just one dman exposed per team
sigh, I know that(I said at the end Las Vegas wouldn't choose him anyway). But what would be the logic to make sure we hold onto Corrado then?
The only reason to make sure we "have Corrado for expansion" would be to fill requirements, otherwise he's irrelevant to expansion because he fills no requirements and despite still be exposed he won't be claimed(like I said at the end of the post you quoted).
Corrado likely won't reach the game requirements to fill that defenseman requirements, and we have Marincin for it anyway. At that point there's no reason to need to have Corrado around for expansion, he doesn't fill requirements and he won't be bait because Las Vegas won't take him. He's basically as irrelevant as Lupul is to expansion at that point and nobody would ever claim that we're holding onto Lupul for expansion.
We're just holding onto him because we want him, every team needs extra defenseman, mostly because of injury. We just appear not to want to play ours unless we're forced to.
