Three things that are of passing interest..
1) England's squad has high representation from Sarries, fair enough, but lots from Tigers and Bath, but only one from Glaws who were easily third best last season
2) The squad appears overloaded, with 6, back three players whereas the highest injury rate is backrow with only 5 dedicated players, one with one cap - you'd expect the reverse of that?
3) The teams selected have lost the old heads and that's been apparent - least to me, when the need to "put a foot on the ball" has arisen (vs SA x2, Scotland, Wales in the 6Ns and most of the 2018 6Ns tbh)
My view is that England are trying to play at too high an intensity, and when they drop off that level, inevitably - they are more vulnerable than a team that plays a more balanced game.
