As you may recall, I managed to get into terrible arguments with two posters on 247, the irascible Sir Virgs and Sanskritsimon, in both instances as I had the temerity to criticise Leach (and Bess) for bowling poorly in one of the Sri Lanka tests that preceded the India series, and both were bowling very erratic line and lengths which would have been unacceptable for an ordinary county finger spinner. It was one occasion when I managed to wind up posters, despite not actually intending to do so, it is just that you had someone who was hilariously protective of his favourites and another who felt he had to defend a spinner no matter what!
Anyway, Leach had clearly improved since that time, although that is because he's can now bowl harder overs without getting smacked too badly when there isn't necessarily too much help for him and still contribute in terms of not getting whacked for a lot of runs so much and even if taking some treatment he's become cannier in picking up the odd wicket when the batter over-commits. He was too predictable in pace, length and flight. He did well enough on very helpful surfaces from that India tour and further back in his career s but it was more that he was saved for situations that really helped slow bowlers rather than any outstanding craft.
It is a tough gig for him to bowl in India though, having not played a proper game since injury and he will be expected to bowl 25 overs plus per day. As big an issue is how Rehan goes. He might come into the game a reasonable amount if there is reasonable help in the pitch, but I suspect canny Indian batting will eat him alive if he isn't really on it. A real sink or swim moment. He had little to lose in Karachi with the series dead on his debut. There is likely to be a lot more on the line in India in comparison.
