Nah, Jason skates circles around everyone in this field. In terms of pure skating (spins, footwork, edges, etc.), I would say he is among the best skaters in the world, depending on the day. (Chan, Hanyu, Shoma, and Jason)
Jason's spins and footwork are clearly better than everyone in the US Nationals field (in terms of edging and flow and difficulty).
Yes, there is no denying that his skating skills are top-notch (I actually like Jason a lot if we're being honest here) but Jason had an underrotation on that 3A that should have placed him below Grant. While I like Jason, I like fair application of the rules the most.
