I,m a bit worried that he has loaded the squad with more bash it up backs than more 'flair player' which will cause the blacks defence no problems just going up the middle.
Intrigued by that, Passed it! Gatland has been accused of playing 'WarrenBall' in the past, boshing it up the middle all day, but I'm not sure which of the backs you refer to.
The only selection I would say is noted for his size and power rather than flair is North. To a lesser extent maybe Payne, Davies, Webb and Henshaw. Please don't say Te'o, because that lad is a balanced runner with the ability to move defenders and put runners in gaps. Don't be fooled by his RL pedigree, he's a proper centre.
None of the following are what David Campese used to call ''smash-it-up robots'':-
Biggar, Daly, Farrell, Halfpenny, Hogg, Joseph, Nowell, Seymour, Watson, Williams.
Every one a flair player.
Neil, which are the 'massive shocks'? As I've said, other than the omission of Launchbury I don't think there are any big surprises. You are definitely right to say that there'll be half a dozen further call-ups yet.
