The current top 4 men are Takahashi, Oda, Kozuka and Hanyu.
The current top 4 ladies are Asada, Ando, Suzuki and Murakami.
If Hanyu and Murakami somehow rock this season, maybe even make GPF or medal at 4CCs, is it possible for them to displace their senior countrymen on the world team?
I think Takahashi and Asada (despite recent struggles) are rather safe.
Oda is mentally unstable at big events and Kozuka hasn't been very consistent. I think they can both be at risk. Trouble is, neither have been geeting consistent high PCS from international judges.
Ando for some reason always gets good PCS and Suzuki mostly rotates and stands up on her jumps. I think unless someone gets injured or somehow withdraws, Murakami will have a hard time making Worlds.
