The walker try was a knock on from that cluster of bodies on the line. There was a south's hand on the ball when Alex Johnston lost it... taffe was off side at the kick where south's challenged the knock on and won ( was the only time i haven't seen the bunker play the entire play leading up to the challenge)...twal was sin binned for the exact same infringement that happened to tigers 35 seconds earlier.. the Brooks disallowed try was try, Yes his hand hit the ball over the top in the action of making a tackle but that's never called a knock on ever. Ken M being off side was extremely harsh but probably correct but again have never seen the bunker rule off side before. The commentary team had red and green undies on they were so biased all night
