One of my tired assertions on here is that the way the LBW rule has been interpreted has been a life-saver for finger-spinners, back in Embers and Tuffers day, batsmen just used to pretend to play a shot with bat clearly behind pad, never given out, actually a remember Tufnell getting one or two near the end of his career, which shocked him as umps became wise to it, finally. DRS has also shown how many times the balls hit the stumps, whilst umpires used to give the benefit of the doubt saying it may turn too much, which was laughabl;e when you think of the likes of Croft, Richard Illingworth not exactly jagging it. The fact that bats have to actually play the ball more now brings in catches at the wicket far more.
Between the uncovering of pitches and these changes was a dire time to be a conventional finger-spinner.
Conversely though, even though Moeen takes a lot of wickets with attacking shots, I really don't think this helps the modern spinner that people go after them. They have big heavier bats, much bigger sweet spots, where mi****s are being slammed for boundaries and not bad bowling can easily go at 8 an over. They take some wickets for it, but bad shots going for runs makes it much harder if attacked. If they hadn't changed the way they view LBWS, finger-spinners would be dead as a breed outside the subcontinent IMHO
Yet it should be said Moeen does rip the ball, on his day probably more than Swann and definitely more than Leach and probably Embers
Emburey though is one I do think would have really done well under the new interpretation, great arm-ball and very accurate, and actually batting wise used to hit a lot of boundaries under the old conditions so may have averaged to be an even better all-rounder, but we'll never know.
