Horne is not a winger. He is a centre playing on the wing. The other 3 have been injured throughout the year.
And he defends there because he is a poor defender. You are the only person who would argue this here.
He's not the only person here who would argue that! All year for the Waratahs he has played second fullback when on defence and second five on attack. In the final I remember him fielding a couple of kicks and then running at pace to bring the ball back up and kickstart an attack. That's what he did all season; that was his role in the team and it worked a treat.
Just as it was when people were criticising Cooper when playing second fullback for the Reds under Link, people just cannot get the idea that he was better positioned for the team there on defence.
Most people have this mantra that says this is where they play because neither can tackle. Well now that Cooper plays 10 when not injured and he stays up in the line on defence, how does that play out? His defence has improved, probably to Beale's level, but neither defend like Horne or de Villiers.
Beale has excellent credentials for a winger. He is very fast over 100m, his 10m acceleration is probably better than Izzy's, he is very evasive and he's not a ball hog. He has the best support play of any Australian player. He started his Wallaby career at 14 and killed it there. As a straight out winger only Speight has more credentials.
He plays at 10/12 because of his creativity - the ability to put others through gaps, the ability to loop and back up. Along with Cooper, To'omua and Folau he is part of a golden generation to rival NFJ, Lynagh, Horan, Tune. What they all have in common is the ability to do something very special that others just can't do.
