While I do agree Pollock maybe wasn't quite as good as Donald, he's extremely underrated in my opinion. In the first 9 years of his career, he had stats to compare with the very best of all time:
76 matches, 310 wickets at 20.7, SR: 54, 16 5W hauls... He performed at an exceptional level for almost a decade of international cricket. It was only after 2003 that he lost his penetrative ability and played second fiddle to Ntini and the others and was just a support bowler... didn't get a single 5fer after 2003. If Waqar can be judged by his peak, then so can Pollock, because while his peak might not have been quite as phenomenal as Waqar, he certainly maintained it for a far longer period.
Regarding his strike rate, 57 is not that bad at all... it's about the same as Walsh. Pollock, while not quite in the top tier, is still very underrated as a bowler in my opinion. And don't even get me started on his all-round abilities. Probably the guy who gets least recognition amongst the great all-rounders, along with Davidson.
His record against Australia wasn't that good, but that team was just ridiculously great.
I don't think too many great bowlers in the 90s did that well against Australia statsistically. Waqar struggled, Donald was merely ok, Walsh produced nothing of note against them bar a couple of great spells. Yet, it's Pollock who's being singled out? meh
