Look lets be fair and go for facts for a change:-
* Kriel is not the sharpest defender and he was useless on the wing against the Aussies as well insofar as defense is concerned. However, he seems to be better when playing with certain players inside of him than he is with others, I agree he has problems - but who are really better than him. There is very little between him and Am as to defense - but personally I am more confident that Kriel on the whole will do a better job than Am and it appears as if Erasmus think so too.
* As to the defense of De Allende one has to accept that in the tests he played in there were defensive problems in 5. On the whole his defense has improved substantially since 2015. This year there was not a single test where his defense was not up to standard. However, the same cannot be said of Esterhuizen, who has other than in the last test a very low tackle count with too high a miss tackle ratio.
* The other refrain is the story about the issue of attacking play by De Allende. This part goes back to his record in the 2014 Super Rugby series - when he set a SR record of 27 line breaks beating 73 defenders, He was MOM of 9 of the 16 SR matches played. Ever since De Allende has been a marked man. It is noticeable that he is rarely tackled by one player - tackles on him are virtually always carried out by 2 to 3 players - and he is virtually never being tackled back. A marked player has difficulty in making as many line breaks and beating multiple defenders as others have.
Be it as it may - I think Erasmus does not agree with our three top world analysts on site - since he has always selected De Allende ahead of Esterhuizen as no 12 center, I am afraid I share his point of view ahead of our local world experts.
Be it as it may the two selected centers tomorrow will have their hands full with Goodhue at out side center, He is in my view the best 13 in the world at present. The same cannot be said of SBW which will be much less of a threat.
