I think that ranking is not the worst yet - the worst was 8 before Sri Lanka sent a poor team to play SA last year.
Now Proteas are going to the Windies for a two test series and it is clear they may soon be below Zimbabwe in the rankings,
The only solution is that the team needs to be selected on real merit - and nobody should "own" their position in the team, I wonder what the team going to the Windies will look like, It is very likely that it will be a foul up too, especially if the selectors continue to select failed players.
The team that should go are -
Adrian Markram, Dean Elgar, Rassie van der Dussen, Rynhardt van Tonder, Kyle Verreinne, Quinton de Kock, Migael Pretorius, Maharaj, Rabada, Nortje and Ngidi.
Backup players also in the squad should be - Rickelton, Janneman Malan, Miller, Linde, Sipamla and Bavuma
