Nobody can convince me this guy isn't overrated. If the team is doing well, he pops off and people are given the sense that he's the cracked, irreplaceable backbone of the team. However when they're losing, he handicaps the team so incredibly hard.
He's a jett one trick, his neon is reasonable enough, but he looks just lost and very ineffective on anything else like raze and yoru which are the meta on most maps right now, resulting in a less synergetic and worse team comp. You can see the difference it makes.
He rarely entries and has a very instalock baiting jett gameplay style. This isn't necessarily right or wrong, and when the team as a whole is playing well it works, but as I just mentioned, when they're losing, it looks worse than my grandma playing. His rate at which he entries site is a complete outlier when compared to basically every other duelist.
Also, the rest of team just pumps money into him. He'll force up, constantly have others buy him, thus inflating his stats like acs/kd. Just now on the 2nd half of split, he buys, swings, dies, gets gun dropped to him by teammate, swings (dashes but insta collapsed on), dies, forces, swings, dies forces (last round anyways), swings, dies, all while teammates buying him are going on weaker weapons just to support his financially demanding and exhaustive style, resulting in a statistical gap growing between him and his teammates when you click tab, which paints a very incorrect picture of who seems to be doing better/worse.
Again, he's good when they're winning, he's one of the worst if they're losing. If you ask me he's genuinely the one of the weaker players on the team besides maybe Simon, who's been going through a rough patch. People are being completely blindsided by the amount of value KK brings just because he has flashy aim.
tldr: bro is overrated
