I suppose they did meet a couple of times, so they probably could cancel each other out. And Andries did not start to improve until 82/83.

I do not know if you have ever seen it, but Minter/MagdziarzIII was a horror show. So much so Harry Gibbs walked out on the bout in the fourth, because literally neither fighter had landed a punch (and that is not an exaggeration, yes they feinted and threw the odd punch, but no one had landed a punch), despite numerous warnings to up the work rate.
