It's interesting that phases per possion and number of kicks both suggest teams are kicking for territory more and not keeping the ball for as long - yet there are still more tackles than before.
Even the fact there's more tackles during less ball in play time is surprising.
Yeah its weird huh; probably need to see turnover stats (and what sort of turnover it is) to see for sure what it is. Also the more kicks was a Warren Gatland stat from the first few rounds of the World Cup, whereas most of the others were from Opta and cover the whole tournament.
