In normal circumstances, Rory McIlroy returning to a scene of triumph would be cause for deep reflection. 

McIlroy finished in darkness at Valhalla when claiming the US PGA Championship of 2014, in what provided a theatric backdrop to his fourth and hitherto last success in one of golf’s majors. McIlroy landed back in Louisville, Kentucky, this week with back-to-back PGA Tour wins to his name.
