G.O.A.T.
Wawrinka can take it to Murray, who has trouble against single-handers. Even Gasquet 3.0 would lose to Nole 1.5 though.
I count 6 single handers in the top 20 - 5 of them have a losing head to head against Murray - the 1 exception has played Murray once, on clay, in one of his post AO slumps.
Stan can definitely cause Murray problems; but not because Murray struggles against single handed backhands.
