Sean O'Brien's season has been so amazing because his on-pitch beastliness is balanced by his utter anonymity away from rugby. Maybe it's his scrum cap, his generic name or his true Carlowness, but I couldn't pick him out of a roll call or a queue for the jacks at Coppers. Subeditors in national newspapers are even confusing him with Paddy Wallace. The man is the anti-Paddy Wallace.
