After reading the above total garbage I will not bother a real statistician with this issue. Lets get this clear for once and for all.
There are two issues that is clear as daylight and those are -
* the win-loss history of teams is a norm used universally to evaluate the performance of COACHES and not individual players; and
* that to nit\pick players and assign an undue influence causing results is the what I would describe with a designated and posted recently on site - is SUPER SHIT since rugby is a team game.
So lets look at the real issue of where such stats are used and that is the evaluation of coaches and their roles in team results and the problems they cause are related to -
* team selection;
* team management;
* actual coaching abilities; and
* game plans.
We were unfortunate that we had three Springbok coaches in a row that ultimately turned out to be unemployable as rugby coaches - as was proved by their careers after their termination of their Springbok coaching careers. The contracts of two of the three coaches were not renewed because they failed dismally as coaches and the third one was fired because of gross incompetence.
Incompetent coaching is what especially Meyer and Coetzee excelled in. Their team selections was a catastrophe - for instance the 2015 RWC squad was by a distance the worst squad ever selected by any coach since 1992. In selection of that squad Meyer's norm were based on reputation and had nothing to do with proven performance of players, That caused a situation that destroyed the chances of the Springboks to win the Webb-Ellis Cup. In the squad of 31 players there were in fact 8 players that were unusable in the competition and when they did play - they were serious liabilities. To pick players that had played no rugby for up to 18 months before the start of the WC was crazy.
Meyer had no real game plan used in matches in the series other than the Blue Bulls game plan who worked when he was coaching that team on Super Ruby level. The result was that the scoring of tries became rare and the role of the flyhalf was reduced to kicking at goal and out of hand kicking, The situation was so bad that he damaged the career and output of players like Pollard badly. A further problem is that he did not understand the game plan of the Lions - the most successful team on Super Rugby level in SA in 2015 - so he refused to pick any Lions players for the WC squad/
Coetzee was even a worst coach than Meyer was and his results were as bad as Meyer's were in 2014 and 2015. It was no surprise that he was fired BY SA Rugby halfway through his contract. His selections were as bad a shambles as Meyer's were - and his game plan was totally nonexistent. However, losses against Japan and Italy were the result of the shambles the two coaches caused. And the termination of the latter two coaches services were confirmed by what happened in respect of club teams they coached after their stints as Springbok coach, Both were fired for being grossly incompetent.
Any players who played in the time of coaching by Meyer and Coetaee would have a tarnished career and to keep that against them is total garbage. Some players like Vermeulen and Pollard never played in the period Coetzee was coaching so there overall record were not tarnished,
Anyway your usage of stats to attack certain of the players you hate is just a total dislocation of what stats are there for. You refer to Mostert as an example of excellence - but Mostert made a major contribution to scoring of opposition tries because of poor defense and dropped from the starting team after the second similar defensive flop under similar circumstances, The man is physically deficient and his main negatives in for instance in the WC final were -
* his feeble tackles in the five minutes the English was attacking the Springbok line - when players he did tackle went forward in all cases and had to be stopped from scoring by other players; and
* roundabout minute 41 in the first half of the final there was a real try-scoring opportunity by the Springboks and unfortunately the ball was passed to him and he spilled it when tackled so he destroyed a promising attack.
Mostert was dropped from the Springbok starting line-up with full justification and will never be in any future Springbok squad again.
This is my final comments on the statistical abuse you are using in this case.
