I did not intend to be rude. The fact is that US team has very few man skaters able to perform quads. Therefore they concentrate on foosteps, spins (and triple Axel) and choregraphy, to gain maximum points on technical elements that are not jumps. That is what I call "US mentality".
It can provide very beautiful skatings, like Jason Brown's today skating.
But talking about jumps, it is riskless.
Max Aaron is very capable of performing quads. And Josh Farris is too, but needs consistency. The only skater you are referring to is Jason Brown. I'm sure Jason will be working on a quad, but for now, he has to make the best of what he has. Nothing wrong with that.
