It would be small. Murray and Wawrinka are the only multi slam winners who aren’t in the big 3…and they both only have 3 slams apiece lol.

Other single slam winners include alcaraz, thiem, cilic, and medvedev. So there would be a few people stuck at one too. Just seems irrelevant compared to big 3

Yeah! Nobody has defended a title there since Federer in 2008. That’s cuz it’s at the end of the season and the best players (Novak, roger and Rafa) are consistently playing later into tournaments thus they come in a little more fatigued/beat up/injured than the competition who loses a few rounds earlier.

Nobody in tennis calls it “the grand slam”, they would say “calendar year grand slam” to refer to winning all four in a year, just an fyi!
