To clarify, by "peak" I mean the best 1-2 seasons of their career; you may choose whichever of those you want. I take it then that most people see it as:
- Waqar Younis
- Shoaib Akhtar
- Glenn McGrath
But was Waqar during his best year (or Shoaib during his best year - I didn't get that clear of response on this) the best of any pace bowler ever in their respective peak years?
