Writing in the Irish Independent, Peter Bills draws a line under the northern hemisphere season.
"Trouble is the countries of the Northern Hemisphere face their day of judgment in three months' time when the seventh World Cup begins in New Zealand.
"So, what state are the Six Nations sides really in? It depends which day and which mood you wish to discuss.

"Yet, the performance against England was of another team."
