After the WC Francois Steyn said he was finished as a test level player. Before Erasmus picked him as a "bomb squad" his career on test level came to an end in 2012 when he ahd serious weight problems. However, Erasmus took him in hand and his weight was a reasonable 110 kgs don from 118 kgs in the period 2012 to 2015.
Be it as it may - in the paper today the writer wrote about him in the "bomb squad" Steyn is already 33 years old and he is too old to feature in future Springbok teams. Unlike Mozart who support experience selections without regard to actual acceptable performances - I believe that player performances are affected by aging and in the end they become a liability rather than an asset in the team. A typical example of deteriorated performances was Matfield - a serious flop in 2014 and 2015.
The aging factor does not only apply to rugby players only - it applies in most codes of sport. There are exceptions - but they are rare. A while ago I wrote that the era when Federer, Nadal and Djokovic controlled is coming to an end nd some people wanted to have a fit about my comments on site, Nadal and Djokovic did not make the finals in the prestigious end of year tournament and Nadal's record since that Championship was poor. Djokovic lost matches which he would never have lost - but he redeemed himself by winning the Aussie Open.
Federer after a year absent from tennis because of two knee operations tried to start a comeback to professional tennis in tournament in Qatar and Dubai. In the Qatar tournament he was disgraced by two players who rarely won anything of note for years and complaining about aches and pains he suspended playing in Dubai next week and said he wants to go back into training before attempting another comeback in May or June. Sad - but I think his professional career is at its end,
The moral of the story is that players try to be active in sport wat past their sell-by date and in the process they damage their reputation. , .
