So history will have only 11 ATGs? That doesn't sound logical.
History should have 11-15 GOAT cricketers. 11 to make the pure GOAT team plus 3-4 who couldn’t make the GOAT team but there is no difference in ability (for example Richard Hadlee might not make the GOAT team as the all rounder quota might be fulfilled by Imran, but Hadlee was a GOAT cricketer). From India you have Gavaskar (GOAT opener) and Tendulkar and from Pakistan you have Imran and Wasim.
1. Sunil Gavaskar
2. Matthew Hayden
3. Donald Bradman
4. Sachin Tendulkar
5. Brian Lara
6. Adam Gilchrist (wk)
7. Imran Khan
8. Wasim Akram
9. Malcolm Marshall
10. Shane Warne
11. Glenn McGrath
This is the rough list of GOAT cricketers that most people will agree on as the GOAT XI (everyone has their own preferences so this lineup might change a little bit here or there). All in all you can add maybe 4 more names to this list to cultivate the list of greatest cricketers ever. You have Hadlee, Murali, and Sobers for example.
Next, you have the genuine ATG cricketers who do not make the GOAT list. These guys are just below GOAT tier — Dale Steyn, Virat Kohli, Steve Smith, Jacques Kallis, AB de Villiers, Shaun Pollock, Viv Richards, Curtly Ambrose, Shoaib Akhtar, Ricky Ponting, Ian Botham, Kapil Dev, Jack Hobbs, Rahul Dravid, and a few more. All of these guys have a genuine case to be GOAT cricketers, and were the undisputed number 1 in the world in their respective eras. They fall short from the GOAT XI for one reason or the other.
Ashwin comes in the next category. These guys are genuine ATG cricketers for their respective countries. Ravi Ashwin, Kevin Pietersen, Virender Sehwag, Javed Miandad, Mahela Jayawardene, Inzamam ul Haq, Shivnarine Chanderpaul, Waqar Younis, Dennis Lillee, Steve Waugh, MS Dhoni, James Anderson. (Some more names that I’ve left out).
These guys are must picks in the playing XIs of their countries. They make a case for being close to genuine ATG cricketers, but they are one level behind the likes of Kohli, Smith, Ambrose, AB, Ponting who are borderline GOAT cricketers.
Overall the distribution will be something like this:
GOAT - 15 cricketers
ATG - 20 cricketers
Country ATG - 30 cricketers
Ashwin is by this metric among the top 65 cricketers to have ever existed, which is a fair assessment.
