From what i've seen, Grabovski doesn't look like a fluke, at all. In fact, he could probably get even better if his shot was a bit harder, leading to only more potential.
He has worked for his goals.
One guy, who i admit is having a great season, but i believe a good portion of that is because of his linemates is Macarthur. Like the guy, but i dont want to pay him something ridiculous next year for what he's done so far.
