No one else has averaged a lot in 2015, but at least Duminy has a bowling option, partnership breaker that sort of thing. I don't rate Bavuma.
That said, SA has an overall talent problem, a batting technique issue, as I have stated before, and with their bowling stocks down it is hurting them.
Compared to Aussies now, the domestic scene was reviewed at high level a few years ago and now suddenly they do not know who to pick, a second string will beat most.
Duminy hardly bowled in india on tracks that were turning square, elgar was prefered...
As for domestic competitions. If you speak to anyone they will say the domestic competition standards have dropped around the world. Our maybe more then others because of the quotas imposed but we are hardly alone in standards having dropped.
As for for bowling talent. We do have enough talent there, a lot of them are just very inexperienced. Radaba will be a star of the future(yes he got smashed in this game on a flat track it happens to even the best) then we have viljoen,patterson,beuran hendricks,savage,pretorius,gqamane,pillans,phelukwayo,ect
Hopefully one of savage,pretorius or phelukwayo can be that allrounder we desperately need.
