AA hasn't proven that he's worth $3M. He's played less than a full season, he really needs to work on the defensive side of his game, his possession numbers were brutal last season, he hasn't shown he can really hold his own in a demanding role and consistently win matchups. $1.9M x 2 is completely fair and is more or less market value for an AA type player. He/his agent is trying to play chicken with Holland and Holland isn't budging, which is good, because AA has no leverage and you can't set a precedent that a kid with no leverage can make a demand and get what he wants "because KHL" and because he scored some goals in a sheltered role.
I keep saying it: AA hasn't proven anything, hasn't really earned anything, has a hell of a lot to prove. Right now, he's basically a third-line winger. It's up to him to show he's more than that. Take the offer, sign the deal, and show the organization that your next contract will have to be a big one.
