I don't see Rubel trying yorkers at the death. Anything else will go to downtown in such a dry weather.
It's capability, yorker is the toughest ball to control - margin of error is so little that, 6 inches either side, it'll become half volley or full toss. On top of that, if it's missing radar, basically a free swing to leg side.
I don't think, on this wicket finishing with pacers is a good idea, which was proved in last game as well (Must be Walshi's plan, no Asian coach would do that with 120K pacers). What we needed was to take the pace out so that it doesn't come on to bat; Mustafiz would have been quite handy on such wickets, but these days he seems to be fit only between March to May.
