This is the worst SA team that could be selected:-
Van der Dussen
The batting side is putrid with three regular failures over the last two years still in the side - Elgar, Du Plessis and Bavuma. The bowling attack is poor as well, with the worst being Sipamla - an obvious quota selection - not considered by the Warriors as their best bowler, He cannot be used as a strike bowler at all.
I think that the selectors - including Boucher and Smith - are not interested in team renewal and team building for the future and that the batting will fail again. And the bowling will also be questionable with a passenger being Sipamla and Ngidi being out of form,
SA chance of winning the test is about 30% - depending how well the SriLanka batsmen do - but against the sub-par bowling attack of SA is likely to help them. And Elgar and Du Plessis is bound to fail.
