Farah has been our best dummy half choice all season especially since Liddle hasn't been available for a large part of it. Tonight, however he looked very slow with his service - especially the way he couldn't bend down and his passing was off as well, which makes me think that his back was definitely a problem.
I have to agree that it's time for him to hang up the boots at the end of this season.
However, Liddle has done nothing to show me that he's the answer. Sure he's quicker out of dummy half, but he does not possess the guile and dummy half cunning of Farah and has no kicking game at all. Also Liddle makes a lot of mistakes in a game and is not as defensively sound. Overall he's an amateur compared to Farah.
