Go back in his history he equally was used as flyhalf, as insid center and as full back from his junior years. Erasmus sed him at full back - but another exmple is the 2019 RWC. When Kriel got inhured Willemse was called up to replace Kriel at center,
AE far better than Willemse is the joke of the century. He is already 30 year of age and at best dumb muscle who has near to zero ball sense - that is where he is not where he should be in defense - also because he as pace problems/
I shall give you another example - both Esterhuizen and Willemse played in the Under 20 RWC and Esterhuixen was satisfactory - but lost the match in the inal when he knocked on the ball with an open tryline in front of him - Willemse became the seleced Player of the Tournsment / Boh played att 12 in the two respective tournaments.
Esterhizen has no idea about the changes in backline play Erasmus and Brown are implementing anyway. Justthink a bit -
* Esterhuizen played in 18 tests - some against extremely poor teams and scored no tries' and
* Willemse played uin 40 tests and his point achievement is 56 points,
You are talking about chalk and chesse here,
