Hmm, taking what the author meant, as in big cricket 'Celebrities' (ie those who transcend the sport and into the whole media starlight), i'd have to go with the following
1) WG Grace - At the time cricket was THE sport in England, but still, Grace was possibly the most famous name in the country (behind the Queen of course). He defined the sport to those who wernt familiar. His name alone was enough to attract the crowds, and for it he could demand stupid money to play. Total mercenary, chasing the money, true sign of celebrity
2) Shane Warne - I think most of the English speaking world knows who this guy is. Unlike in Grace's era, cricket is not the biggest sport in England, and before the Ashes tournament most people would be hard pressed to name more than one person on the England team, let alone any other country. Bar Australia, because Warne is a name synonimous with cricket. Ever since THAT ball to Gatting, the name Shane Warne has been banded about with almost trepidation. Whenever talk of the Ashes comes into everyday conversation, you can guarantee the non cricketing fan will mention Warne. Of course, certain scandals have made his name more prominent to the non cricketing fan (lets face it, how many cricket scandals are there!)
3) Andrew Flintoff - Before the Ashes tournament most people would be hard pressed to name more than one person on the England team, but if they did, it'd have been Flintoff. He is simply crickets man of the moment. In England he is a national tresure, and is being thrust into different spotlights faster than he can rack up runs (i mean, he's plannin on doing a duet with Elton John!). He is to cricket what David Beckham is to football (with a better looking wife and without the stupid childrens names)
4) Imran Khan - If Flintoff is the cricketing Beckham, then Khan is crickets George Best. Flash, stylish, pop star looks, and enough skill to make a team quiver in the dressing room. He paved the way for superstar cricketers. Flashy pads, tabloid private life, high profile wife. If i was Pakistani, i'd probably have him at no 1, because i'm guessing the effect he had in Pakistan was absolutely immense. As it is, i can only go on what i know, so he can feel a little agrieved at being so low (as if he cares)
5) Brian Lara - Odd choice mebbie, but 1994 was almost Lara-mania (and no i'm not on about the Tomb Raider games). Every record there was, he smashed, and everyone knew the name, the face, and the sheer talent. Just as likely to be on the front pages rather than the back, for his cricket exploits alone, puts him in a position to challenge for this no 5 spot.
Now please remember i'm 22, only really picked up cricket in the last 10 years, so my results are skewed towards the now (obviously grace and khan i've looked into a bit
)
So yeah, Botham, Richards, Bradman etc are missed. I'm sure they'd make others top 5's, and i shall certainly not argue with that, they deserve to be there
