Sadly a large number Gilchrist's innings are vastly under-rated (or rather don't receive as much hype). He, along with Malcolm Marshall, will be the first names in my ATXI.Bloody oath. Gilly was insane. I recall a tour match in 96 , WA v WI at the WACA, Gilly was captain and peeled off a first day ton in blazing fashion, Kim Hughes said on commentary that Gilly was the cleanest hitter he had ever seen. Was a bit of a shock at the time but with the next few years it would be a standard comment about Gilly, so clean was his strokes.
Bishop was very very quick before his back injury. I do recall batsmen who faced Bishop (during the early 90s) and Waqar/Donald during the same time rated Bishop as quicker. He gave Robin Smith a torrid time and broke Indian opener Srikkanth's arm in his debut ODI series. After his comeback in 1995 from the back injury, he was a shadow of himself, and the stats clearly reflect that.
Bishop from 1989-93
