I don't think Yasir will be dispensed with in a hurry. His footwork is very positive and technically he is very sound. I agree that he tends to give his wicket away but for me he's done enough so far in his career to perservere with. I think the opening spots are more problematic, at the moment I still tend to favour Taufeeq and Farhat who did put on a few hundred run partnerships together. Taufeeq especially has made decent scores against Australia and South Africa.
