The main difference between Eddie Jones and Allister Coetzee - aside from the Aussie's mordant wit - is that the former knew from the start which players he wanted in the England team, while it took the latter 120 minutes of Test rugby to come up with a more or less settled Springbok combination. That was understandable. Coetzee had a history with his players. As a local coach he could not avoid local reputations and local loyalties.Jones had no such hang-ups.The past was none of his business and neither were previous convictions. He could appoint the recidivist Dylan Hartley as captain of England with hardly a glance at the hooker's rugby rap sheet.Inscrutable Eddie also has a brutal dispassion about his selections. When Luther Burrell did not measure up at inside centre in the first Test against Australia in Brisbane, Jones had him off the pitch within 30 minutes of the kick-off, moving Owen Farrell to No 12 and bringing on George Ford at flyhalf.It was a decision not many coaches would have had the courage, or the chutzpah, to make. It turned out to be the most inspirational of that series, which the English sewed up on Saturday in Melbourne.The jury is still out on whether Coetzee had got it right by Saturday evening at Ellis Park. Was his decision to finally give those Lions players a chance the turning point in a great Springbok comeback, or did the Irish succumb to Highveld altitude? All might not be revealed in Port Elizabeth on Saturday.If the Boks manage to find a coherent game plan and win the series, it could still send out the wrong signals for the coach.There remain question marks over some of his selections: Is uninspiring Adriaan Strauss the right captain, is JP Pietersen past it, does Frans Malherbe need the hairdryer (along with a haircut), did Damian de Allende's alarm clock wake him up in time on Saturday and should François Louw be called Flo or Flou?Of that lot, it is Strauss, Malherbe and Louw who are the main concerns. Something is wrong with the Springbok scrum and Nick Mallett is right: it's about time the Lions hooker Malcolm Marx is given a chance. He was, after all, built by the same firm that brought you Bismarck du Plessis.But it's comforting to know that Michael Cheika, the Wallaby coach, has bigger problems than Coetzee's. And even in New Zealand they are agonising over selections despite what looks increasingly like a 3-0 sweep against Wales.If the All Blacks thought they could get on with life as normal in the absence of Richie McCaw, they have to think again. Sam Cane was one of the weak links in their pack against Wales in Wellington last weekend - until Ardie Savea replaced him. The Boks can achieve a similar revival of fortunes if Coetzee can bring himself to choose yet another Lion in Jaco Kriel.Coetzee, through no fault of his own, was a late starter in his new job and time has already caught up with him. He will need to get his selections right for Saturday in Port Elizabeth. It will be his last chance before facing the brutes of the Four Nations (aka the anodyne Rugby Championship), which kicks off in just over nine weeks' time in Nelspruit...
