This is a crucial innings in Buttler's test career. With Anderson and Broad reaching middle age there's a good case for bringing in Curran instead of Buttler. We saw in the 1st test the devastating consequences of going down to just 4 bowlers.
If ever there was evidence one day cricket is ruining test cricket we're 64/8 and yet 9 out of 10 of our batsmen have hit at least one boundary, the only one to miss out being the skipper Root.
