Ronan O’Gara: How the 'phantom attacker' haunted James Lowe for decisive Welsh try

It is undeniable that James Lowe was the central figure for the George North and Louis Rees-Zammit scores

We can resort to ifs, buts, and maybes in relation to last weekend, but if we do that, maybe we are missing some key points.

Wayne Barnes is a genuinely excellent referee. He is the best out there on the rule book and rugby’s ever-changing laws, as perhaps a barrister should be. His penalty in Cardiff against Tadhg Beirne for being ‘in the tackle zone’ was a new one on me, and sounded like one of those makey-uppy things, but I am not going to challenge his authority.
