I always maintained we need to look beyond beyond Sanju but everyone felt Sanju had scored three centurys and was not playing well since he is out of his batting position due to Gambhir ‘s politics.
Good player manages to play well in any position example dhoni, yuvi, uttappa have played both in top and middle order.
having said the above, I feel Sanju will be played to keep left and right combinations and I personally feel he is better keeper than ishan kisan
