In defense of Patrick Chan, his first Olympics in 2010 was won by a man who attempted ZERO quads. They weren't worth enough points to be "worth it" in that version of IJS. And then, in 2011, Patrick shows up with 2 consistent quad toes and changes the game (literally) because he was doing quads while keeping his commitment to skating skills and choreography. So, people decided to do quads again to keep up with him. Dai, Javi, Yuzu, and the rest did only toes and sals for a long time, until Boyang came along with a consistent 4Lz. (Dai's attempted 4F at 2010 Worlds was 2-footed). Patrick did add a 4S in his last 2 seasons and landed a couple nice ones in competition. And then, through personal choice and circumstances (details of which we'll never know), he went back to 2 quad toes for his final season.
My point is, Patrick did not train as many types of quads because it was not expected/needed in competition in his heyday. Saying Patrick didn't do as many quads as others so he should somehow be discounted is like complaining that Paul Wylie never included a quad. Of course he didn't. Nobody has ever claimed Patrick is the best quadster ever, although he showed great consistency on his 4Ts overall throughout his career.
Exactly. Patrick didn't reinvent the quad. He reinvented the "overall great free skate containing two good quality quads".
