Veteran Australia off-spinner Nathan Lyon, expected to play a vital role in the upcoming five-Test Border-Gavaskar series, is a more "complete" bowler compared to India's Ravichandran Ashwin, former South African bowler Paul Adams, who became popular for his unorthodox action, said on Tuesday. Lyon, with 530 Test wickets, and Ashwin, with 536 scalps, are the two most potent spinners in the world but Adams, whose "frog in a blender" action made him quite a celebrity during his playing days, said the Australian had the ability to trouble batters on pitches around the world.
