England hasn’t had a settled opening pair since Andrew Strauss retired in August 2012 and left Alastair Cook in search of a partner. He never found a consistently successful one, though a number of those who walked out to the wicket with him did score at least one Test hundred. Some of those tried and discarded are still playing; Haseem Habeeb may open in the Third Test at Headingley this coming week. By my count, there are a dozen still active county players who have opened for England. The list includes Cook himself, who retired from Test cricket but continues to play for Essex.
