While Murray isn't the same level as the Big 3, I disagree about his level of class. He stands up for women in tennis, and he's also the funniest of the Big 4. He may be grumpy on court, but I think he's very classy off of it. I have a problem with the "Holy Trinity" appellation. Too religious for me, or slightly blasphemous. Murray may be in that odd place by himself, but I still think he deserves Big 4, more than Wawrinka deserves being in the same mix. I would stick with "Big 3" or "Big 4." However much Murray has trailed behind, he stayed close in the conversation for a lot of years with GOAT players. He's separated from Stan by 2 gold medals, the #1 ranking, YE#1, and a lot of MS caps. While I agree that he's not Fedalovic, there isn't really anyone else to touch him for accomplishments.
