I must admit, this is one bok selection that baffles me. The only thing that come to mind is that Rassie is so invested in transformation that I smell a quota here.
I couldn't find anything of Moerat on web nor can I recall any man of the match performance that he has had. Even when you look at bias player ratings, he still scores average to low.
Neither do I see him actually win line outs, drive mauls or being an enforcer.
I definitely think Rassie need to dial it back a bit now
