Well who does make as sachin' s bats?
It really should be stated by a company that the bat they sell is" based on" so and so' s bat, and not his/ her actual same bat in every way.
What would be cool is to put a test batsman's bat up against the same level bat bought in a store , and thus the comparison would be the truth !
A great deal of players use an off the shelf bat, Ian Bell and Graeme Swann are two very prominent examples. Bell handpicked his Kook sticks 2 days after us last year, and in the following matches could clearly be seen using a Recoil 900 (not even the top model) before the 900 sticker was removed. Fair enough, this year he definitely isn't using a Menace, as the shape is wrong, i imagine his Recoils have been re-stickered.
Swanns GM Epic is as off the shelf as it gets.
This sort of thing happens in a number of sports. David Beckham's predators were very different to the boots millions of people purchased every season. As a goalkeeper myself at a couple of football league club academies when i was in my teens, i know for a fact that goalie gloves for pros are very different to the stuff you can buy in store.
As said above, advertising happens in all walks of life, i highly doubt Holly Willoughbooby and James Corden use a windows mobile phone.
Also, nowhere in any manufacturers catalogue does it say 'this bat is the same as player x's bat in each and every way' - they generally say 'used/endorsed by player x'
If player x is using a bat with GN Oblivion stickers on, then by definition it is an Oblivion. I think everyone realizes that Alastair Cook won't be using an Oblivion 4 star even though he endorses it.
If someone really wants player quality wood, then it is possible to get it (or very, very, very close to it) if they are prepared to pay top whack.
