Chen - fractional favourite due to GPF, his scores, and Hanyu being injured. But the Men category is just unpredictable, last results being Boyang wining 4CC and 300+ points. Never count Boyang Jin out by the way, he might just get on that podium.
Zagitova - If clean, she might destroy everyone on technical and rightfully so, but that is a big IF. That being said, her SP when clean is just wow.
Savchenko/Massot - they have the better programs this year (even if S/H have quite the amazing programs too) and especially the better LP, but can't afford mistakes. Neither do S/H. If both make mistakes, Candyman might show up.
Papadakis/Cizeron - again fractionnal favourite due to GPF, well-received programs too. Can't afford a single mistake or a loss of level, just like V/M.
