Stupid argument. Smith is the Australian #9 and captain, the Dally M player of the year in '06, and is an outstanding rep player. Farah is the Dally M hooker of the year, and has outplayed Smith on both of their meetings this year.
Supporters of Farah will say that incumbency denied Farah the NSW and Kangaroo #9, rather than talent, and that Smith's performances at a rep level are no indication of superiority because Farah hasn't been given the chance to prove himself in that arena. Supporters of Smith will say that Farah's Dally M award came about because of the relative weakness of his team, and that being a superior player does not mean you cannot ever be outplayed (Noddy schooling Johns when the Sharks thrashed the Knights a few years ago comes to mind).
If you think Smith's the better player, you're not going to be convinced by any of the Farah arguments, and if you think Farah's the better player, you're not going to be convinced by the Smith arguments. The argument's quickly becoming circular, and more than a little ridiculous. Stop wasting your time, people.
