Vrana shouldn't stick unless he's outplayed Milano for that spot. One of them in the line-up is good to provide offense, i think i like Milano more for that spot. But Vrana making the roster over Cristall sends the wrong message. AC has clearly outplayed him and they both require baby minutes so it's not like Vrana has the veteran card to play here.
Despite Vrana being a former Cap, this is a business decision. You keep the guys that give you the best chance to win. Vrana still has time to shine but as is, he doesn't seem to have done enough to pass Milano and there is no reason for him to be ahead of Cristall on the depth chart, either.
Even if Cristall is sent down for wrong reasons, if player on a scoring role were to be replaced on the line-up, would you really want to give that spot to Vrana over Miro? I don't.
I do hope Vrana gets a role on another team. Perhaps the Blue Jackets?
