I saw some stats on squad breakdown
NZ 2015 had this: 3x Hookers, 5x props, 3x SR, 6x backrow, 3x SH, 3x FH, 4x centre, 4x back three
This reflects where the knocks will be (backrow)and where you need briefed and practised players in terms of organisational skills/knowledge- SH and FH
England have loads of back three players, a tyro SH and only 4 experienced back row players
Looks odd, but what do I know!
