When Shane Williams took just two minutes to achieve what neither Australia nor Italy could achieve in 80, the complexion of the first quarter-final changed in a heartbeat.
It might sound wise after the fact, but in those minutes sparkling first few minutes, all the concerns Ireland brought into this World Cup resurfaced. They've never made a World Cup semifinal, most of this team will never get another chance.
Wales, on the other hand, have a crop of youngsters who have no history of heartbreak and no fear of defeat. The quick score just served to further embolden them.
During pool play, Ireland's methods had been more about attrition than ambition. Armed with a stingy defence and a dynamic back row, Ireland first fortified themselves against the concession of cheap points, then tried to break the backs of their opponents.
Wales' pretty try, which owed most to Jamie Roberts's superb catch of a midfield bomb, gave them pause for a rethink.
