As a non-Australian:
1. Bradman
2. Lilee
3. McGrath
4. Warne
5. Miller
Top ten would be
6. Chappell
7. Lindwall
8. Waugh
9. Harvey
10. Ponting ? (pusing into top ten)
McGrath is a ****ing freak. I mean, thats the only way to describe this guy. He gets wickets everywhere, without being a speedster. He is economical, and deadly at the same time. People rate Lilee higher, and he may well be, but if I had to pick one person over a 10-15 year period to revolve my pace attack around....it would be McGrath.
He is sort of like Kumble, in that he is not very flashy, and people don't think of him when talking about real turners like Bedi, but when you actually look at their contributions: All they do is win.
And that, in the end, is what counts. How many times has McGrath steamrolled the opposition's top order? Thats what clinches it for me. He gets the wickets of the best batsmen of the opposition.
