Ok, now that you ask for it
.....
Imran
Averages sub 30 in all countries that he played in, performed well against most opposition and most conditions
Since you mentioned Waqar's SR Imran still got cheaper wickets even if 10 deliveries slower
Ran through some very good batting lineups (2nd highest Man of Match ratios for any fast bowler)
As you talk of peaks Imran has the highest post war peak of any bowler (let alone a fast bowler)
Performed extremely well against the greatest team of his era (arguably the greatest team ever to grace the cricket field)
Care to make a case for Waqar other than listing down the aesthetics of his of his bowling action? Or maybe the new troll on the forum plumbinfront might like to make a "fair case"
