Biff's technique is flawed

I think what the Smith supporters seem to be missing is that Smith has a flawed batting technique. Has he scored many runs for SA over the years, yes, granted. But the fact of the matter is that teams have now devised a system to get smith out quickly. Look at the fall of Smiths wickets the past few innings and you will notice that his wicket falls due to him playing one of two shots...pushing to a wide ball on the offside, or forcing a straight/offside ball to the leg side and missing it (out caught or LBW). Compare this to the balls that got alviro, or Faf, or Michael Clark...they are all good, nearly unplayable balls that gets their wicket. Not a wide ball that Smith nicks or a straight ball, bowled at pace, which smith tries to play legside. This is why Smith should be dropped... His batting is technically flawed and even yesterday's win does not change that.
