Not my sort. He looks a bit too short for me to. Looking through photos of them both he looks to be about 5ft 6in. Roux is about 6ft (judged by photos showing him alongside OP who is just over 6ft in his prostheses).
I found this in a National Newspaper in the UK. It doesn't state his height but infers he is short.
Nel, nicknamed "the pitbull", is diminutive and pugnacious and a sharp contrast to the tall, silver-haired, urbane Roux.

Interestingly, I also came across this piece of information that I did not know but it goes someway for me in explaining why "Oldbu**er" is so pompous. He has come good, but late, from quite ordinary beginnings and looks as though it has gone to his head. He seems to have a need to give an air of superiority. Something we don't see in Roux and Nel.
"Rouxs junior advocate is Kenny Oldwage who was admitted to the Johannesburg Bar in 2002, prior to that he was a police officer."
