I think Anze Kopitar will be the best. The Kings now have some more players to play with him and if he plays a whole season injury free he's a good point a game player.
I'm gonna go with Malkin. Of all the rookies he had the most points and he won the Calder Trophy. Although he did have Crosby on his team to assist him in some of his goals, but even without Sid Malkin would be a star player.
