South Africa has copped a fair amount of criticism for the decision to transform middle-order batsmen into openers. Stiaan van Zyl struck a superb century on test debut as middle-order batsman, but when transformed to an international opener, failed.
Stephen Cook started his international career as an opener with a century and has struck three tons and three half-centuries since then, but was axed after only managing 57 runs in his final seven innings.
