Erm how not? I was being generous in giving them third given as they may have lost out to Fiji in a 3rd and 4th place play off.
England had two tough games, and lost them both. Home wins against the might of Ireland, Fiji and France hardly constitutes a success now does it? Given that the players themselves went on record as saying that anything less than the final was failure I hardly see how you think it is not?
McNamara's remit would have been the WC Final at least. Given that only 2 out of 3 teams were ever gonna get there and they are the spare part, he failed. Simple.
