Elgar is big in Tests but not in T-20. He won't make it into 18 men's squad as well.
Depends on merit. At least compared to the other South African batsmen, Temba Bavuma has underperformed at international level. On top of that, he is more suitable for the test format. Dean Elgar's case is similar to Steve Smith of Australia. He is also not suitable for T20 format. On the other hand, Sisanda Magala went for a massive amount of ZAR 5.4 million. Lungi Ngidi was sold for ZAR 3.4 million. So race played hardly any part in this auction. It needs to be seen though, whether the South African Board will force quotas for the franchise league in the long term.
