For the second part, you can blame Ashwin and Siraj right?
I am not blaming Jadeja's batting, but after 2021 England home series Axar should have got chance regularly ahead of Kuldeep Yadav, that's how roles would have got cleared to Ashwin and Jadeja. Jadeja main thing is batting in this team. If not, there is no place for him in this team. He should go and rest and Axar should get chance at Pune and Mumbai. Will be definitely helpful. You cannot select players like Rahul on Indian pitches on the basis of two centuries in South Africa. He made huge blunder in final. Nobody can forget that. That trophy was ours.
By your logic, WC2003 loss was never responsibility of Zak, Nehra and Srinath. You never gave chance to Agarkar and Bangar strengthen bowling over PATHETIC Dinesh Mongia. Who on the earth selects second spinner on south African pitches?
