1. Could Crosby deserve one? Maybe.
It's easier to play defense than offense. Crosby is the best in the world. As he grows old, maybe as he gets a bit slower he won't be able to perform offensively as much, and will concentrate on mastering the defensive game a bit more (like yzerman did). He certainly has the talent to do so - and if he does, he could definitely be in the running, and eventually win one. It should be easier for someone like Crosby to excel defensively than it is to do so offensively.
2. Will Crosby win one, whether he deserves or not? Again, maybe.
If Crosby is having an all-time great offensive season, while also being one of the best defensive players (ie - let's say this coming year he scores 120 points, and most agree he's the 4th-5th best defensive forward in the league) - it might be enough to garner the votes necessary to win.
So - it's possible.
