I'm high on Mailloux. But, let me debate your definition of talented. You called him talented because of one elite skill: his skating. So I would at this point call Mailloux a talented skater. But, I wouldn't call a guy like Drouin, who has more than a few elite skill sets, talented at NHL hockey. Sure he's highly skilled. But his lack of hockey sense doesn't make him a talented hockey player. Just a talented skills competition guy, but a rather useless hockey player.
We'll have to wait and see about Mailloux's other skills, especially his ability to process the offensive and defensive sides of the game at NHL speed, before we know his NHL talent level.
