I don't think Yuzuru should have 5 quads in his program. He should focus on other elements and on consistency. Many quads doesn't make you automatically win, we saw it with Boyang, with Nathan, Uno even Chan had 3 quads. None of them has broken Yuzuru's 3 quads WR yet, even with inflated scores, for a reason
As long as Yuzuru has a good skate at the olympics, it doesn't really matter if he doesn't win. He is the only current skater, who is a olympic champion, 2 time WC, 4X GPF champ, 4x national champ (so far) and who has broken 11 WR. All these things speaks for itself. Whoever is going to win the olympics, won't achieve as much as Yuzuru did. Olympic champs come and go. Many of them r**** and are forgotten, but not Yuzuru
