Sorry BQ and TBQ I think Curry carries well and Underhill tackles everything in the stadium but would still have Robshaw there as it's not just the turnovers but slowing oppo ball down where he's better. Plus he tackles!
No need to be sorry! You are wrong though :P
Curry and Underhill are both breakdown specialists and also frequent top tacklers. Their work transitioning from tackler into immediately getting over the ball is what has earned them their call ups. They're just both quicker in those situations (and in broken field too) than current-day Robbo - youth definitely helps in this regard. Robshaw should be in there ahead of Shields in my opinion, pushing Wilson for the 6 shirt.
I genuinely think if the progress Robshaw has made at the breakdown over the last 12-18 months had come an RWC cycle ago, he'd still be holding down a starting shirt for England. It's all come a little too late for his England career I feel - but on the flip side, great for Quins for another couple of years! And who knows, all it takes is for Eddie to injure one of his back rowers... which, let's be honest, would not be hugely surprising.
