Is it a case that the talent simply isn't out there or is it that the talent is but because 2020 and one day 'skills' are now more valuable to a player and club, players simply are not growing up/learning to value their wicket ? Warner has a good test record but he's not really a test opener, he's a one day player. Is his avg down to poorer bowling or flat wickets (which allow his one day stroke play)?
Go through other test sides and you see the same issue arising, hence these one sided, quick scoring tests. Is the art of test match batting being lost? I believe the system simply isn't set up to breed cultured players who bat long and value their wicket.. It's set up to breed one day players
