Hard to tell, really. He's certainly capable of putting up that kind of production ... but he's been prone to wild swings from hot to cold for his entire NHL career. I think it would be wise not to gamble on him if this is a fantasy league kind of issue.
I'd venture 35 to 40 is the safe side for Vasicek. If he does better, great ... but I figure he's good for at least one prolonged slump.
