Here's an unpopular answer, but I'll add Kygrios to the mix. He had the 1980s bad boy mouth on him. It was honestly a breath of fresh air hearing him fire from the hip, instead of always giving politically-correct rehearsed answers that we mostly hear these days. I miss the days of Connors calling Lendl a "f****** pusher" during the match, or when Lendl in an interview said that McEnroe can't beat him anymore(that ticked me off big-time when I saw that, but I respect that these days). Don't get me started with McEnroe. That guy was a riot. When interviewed after losing a slam final, he was asked what he thought about the match. He said he never received that much money for losing. Funny stuff. Kyrgios was pretty funny when interacting with the crowd in court 17 when I was at the USO in 2018. Yeah, he's a clown. But he was entertaining. My friends that weren't really tennis fans at the time thought Kyrgios was the most entertaining. He was spinning his racket with neon-colored strings and chatting with the crowd. What a clown. But he was entertaining. When you watch him live, it reminds me a lot of the retired pros playing the PowerShares tourney. They were half-serious. They wanted to win, but clowned around at times. Kyrgios' serves look so ridiculously easy when seeing him play live. Part of that was his clowning around. But the other was part was his natural motion.
