Like AK said, there isn't any reason to be to excited. He's only played a little bit of SG Ball, it's not like he's playing in a harder combination like the Toyota Cup or NSW Cup. So there is nothing to say he's going to be superstar or anything yet. And if he does come, he won't be playing First Grade for quite a while, if at all, with Gidley/Henry/Mullen/Rogers in his way.
But i have heard from a few doggies fans, that he has all the skills, and they reckon he's just as talented, if not, more then his brother Ben.
