Murray also pretty much single handedly beat the US, French and Aussie teams, but you've forgotten that obviously as you were so focussed on Murray just beating Goffin.
TBH, whatever big title Murray wins now is just cherry on top. If Murray was asked if he would settle on a career with a Wimbledon, US Open, Olympic Gold, Davis Cup and 10 Masters back in '05, he would have chomped your arm off. We are in the midst of greatness with three tier 1 greats in Federer/Nadal/Djokovic, so to achieve what he has achieved is amazing. In the NBA, if it wasn't for Jordan, HOF guys like Stockton, Malone and Barkley would have won multiple NBA championships. Same goes for guys like Roddick - he surely would have won at least 3 Wimby titles if not for Fed.
