Thats pretty simple to understand why all the past cricketers talk like this. In the not too distant past they too had performed in the same fashion. If you go strictly by records you will see that no past cricketer has played a back to back epic innings. They had one great innings and then stayed on in the team going through the lows only to bounce back when they knew that their positon was under threat. So it is unrealistic to expect any better statements other than these.
