The engagement bait is unreal, but I'm all for a discussion. Leo's individual numbers are what make people call him the initiator GOAT. Sacy may have a Champs trophy as well as a Masters trophy, but Sacy has never been an outstanding fragger - his utility is great but that just makes him a good support role player. Leo had the capacity to put up numbers, provide support and survive to win his team the round. He is the exemplar way of playing to win.
Mini is an incredible coach, but no coach is invincible. They lost to LOUD in Champs and I would argue that LOUD were basically in FNATIC's head. They had all the pressure to go 3 for 3 in that year's trophies and solidify the dynasty. Chronicle was not playing particularly well against LOUD on both instances at Champs.
As for 2024, FNC lost to a rising KC and TH who defied expectations so there was no Madrid. FNC really didn't seem as dominant as 2023 and that was just part of the adaptation to a new coach. They eventually beat TH in Stage 1 and it was Leo who really pulled FNC over the line. That Breeze match was some of Leo's best since he just took over. He apparently took over the calls from Boaster and continued to fry. Leo at his peak performance was unreal and it's a shame that it couldn't be sustained due to health reasons.
