Not much to add really, except that I think it’s unfortunate that three key players [Stokes, Bairstow and Buttler] seemed to me to be clearly way out-of-form / injured / knackered, and unable to contribute much, right when we needed their talents most.
But I’d agree there’s a systemic problem that probably goes beyond individual failings etc.
My main question is simply why do other countries seem to have their Test cricket thriving despite the other forms of cricket - perhaps even in fact because of the other forms of cricket - while England seem to be falling to pieces?
