Don't know much about Curran. Root hasn't been the same since he became captain. Happens to a lot of players and it seems many don't regard him as a very good captain. The previous English captain Cook had similar issues. His batting seemed to suffer from then on or at least not be as good. It's happened to some of Australia's former captains as well. Making elite players captain doesn't always work out for the best.Smith is just insanely good, and England have an inability to close off innings even when bowling well. Roy is struggling at this level but there is genuinely nobody else available to open, while Root has been poor this test. I believe in stokes and buttler enough that I don't think there'll be a winner of this test, but for the next one England need a nice green top, Sam Curran in the team (and opening the bowling with broad), with foakes into the side as well potentially.
Archer is just excellent, fantastic match from him
