They've conceded 4 tries in 4 and a half games of rugby, I wouldn't call that "not working". They're not the most inspiring pair in attack, and Ringrose is an improvement but I wouldn't look at those games and dismiss them, no one has done enough to knock that as our second choice centre pairing in my opinion.
