Nathan Chen, maybe, assuming he's healthy.
You'd think I would have managed to remember him from the past EWC's, but no. He also has good enough PCS potential to do it, I agree. Jin is a throwback to early days Chinese skaters scratchy-ness and I don't mean that as a compliment (just in case there was any doubt). Hopefully Chen stays injury-free, if not for this season's JW then in the future. Both him and Shoma have potential to turn into great skaters & performers.
