There isn't enough cap space to call up Vrana unless they LTIR Oshie. This has been covered numerous times.
I realize it has been covered. I wasnt saying it was currently possible. I was merely saying that we fans are dying to see our shiny new toy up close and personal in an NHL sweater, especially because he has hot hand right now.
As for LTIR, it still bears watching because, as others correctly pointed out in the Kuz thread, a) the duration of Oshie injury may be murky even to Oshie and team; and b) LTIR placements can be executed retroactively.
So we may see Vrana yet, nothwithstanding current cap issues.
