For Johannesburg i think theyll stick with Bess to rotate the seamers, if Archer is fully fit then Curran looks the man to miss out for me.
Wood, Broad, Archer, Stokes and Bess looks a good attack for the Wanderers.
Five seamers seems overkill and Bess can contain allowing short spells from the really quick Wood and Archer with Broad opening the bowling. Stokes isn't normally overused these days as a seamer so Bess will play a vital role.
Sam Curran hasn't any real pace and the Wanderers is a ground where real pace can pay dividends, the tail will be longish but Bess has made a test fifty and Wood showed he can be a useful hitter.
Buttler is under serious pressure for his place and urgently needs to contribute with the bat, Ben Foakes looks almost a shoe in for Sri Lanka and Buttler won't find it easy to get back in. Both Foakes and Bairstow are his competition and both will be eyeing up the keeper role after Sri Lanka.
