With respect, I am not sure if it's luck if another team drops their catches. Particularly with England, due to the lack of pace in our attack over the years, we've always relied on catching as a mode of dismissal, so if we're off in the field, it's our fault. No one's ever sorry for us if we drop half a dozen in a day for that reason, which often did happen when we had a bunch of poor fielders like Tufnell and Mulally playing.
I can't remember exactly, but a lot of the chances in that first test were smacked pretty hard. There weren't any dollies. Pope also got out to a one in a million catch at gully when he was well set, and you could say that was mighty unlucky.
Ultimately, England outperformed New Zealand in the first test and won by eight wickets.
I think the degree to which England have been torn apart in this final test (which I will admit, is hugely embarrassing and takes a bit of the shine off the series win) has skewed perceptions of what went before. Before this test, I only felt that Henry had bowled well for NZ. O'Rourke definitely came to the party in this test and showed what he can do bowling a better line, but he was erratic before that.
