More or less, but probably without the slight sneer placed in the emphasis.
To me greatness in any field encompasses so much more than simply being the best at it. Greatness implies the changing of what you found into something better and being, to a degree, an aberration amongst your peers. In cricketing terms, it also involves for me an element of a player's presence. Warne, for instance, scores much higher for me in those areas than McGrath. This is not a slight on McGrath - in general terms he was a 'great' cricketer in all those categories, simply not the 'greatest'. But in a purely achievement/results/consistency framework he was probably as good or slightly better than Warne. However he brought little that was new to the sport, apart perhaps from a new standard of consistency and longevity (except others had played as long as him anyway), and did not really leave it different from how he found it in the manner that a Grace, a Bradman, a Worrell, Imran, Warne or Gilchrist did. And while he was menacing to opponents and made his teammates walk taller, he didn't have the same presence on the field as a Warne or Richards.
Hope I've explained that distinction, which is a bit like pornography in that I know it when I see it, somewhat clearly there. It's only my personal take on things.
