Zaheer Khan isn't that good when you compare him to the others who have emerged this decade. Steyn, Lee (He has played the majority of his career this decade), Asif, Bond. He has an average over 30 in Test Cricket. Hardly anywhere near 'threatening'. Asif plays on the same deadpan pitches, yet his average is in the low 20's. Steyn plays in bouncy pitches, but he has pace and still can be a problem on dead pitches. Zaheer has 220 wickets at 34. That's not anything more than an ordinary bowler. Yeah, he has become much better as of late, but he has lost pace. Chris Martin has 170 wickets at 33, but no one calls Martin special. Zaheer is easily India's best quick bowler right now, and this decade, but that doesn't really say much.
