While they keep bowling the sixth-seventh stump line throughout, the reluctance to place a fielder at gully for the entire duration of Rahane's innings against pace was interesting to note.
He started staying inside the line a lot to work the ball on both sides of the pitch.
While the change in angle might have led the batsman to expect an inswinger, he bowled an outswinger.
While the angle prevented the ball from swinging away prodigiously, it moved enough to force the batsman to play outside the line, which resulted in a huge gap between bat and pad.
While the talk is mostly about his mystery and how it's making it difficult to pick him, we must not forget that it's not just the variations that he brings to the table.
