I didn't vote because it seems like any of those three could take the title, or it could be someone else (Aliev or Kolyada if either manages to skate clean).
Uno would seem to be the favorite since he has come closest to winning, but he has always been a bit of an underdog - will he be able to carry the weight of Japan's expectations alone?
Jin could absolutely harness the Force and take it all but he would have to skate two almost flawless performances to do so.
Chen has demonstrated that he has the ability to win by absolutely crushing the field in the free skate at the Olympics, but that was skating as someone in 17th place with nothing to lose. Like Uno, I think he will be under a lot of pressure.
To me the dark horses are Aliev and Kolyada - both have the content and skating skills to challenge for the podium and possibly the top spot depending on how everyone else does.
But if everyone goes clean it should be Chen due to his tech advantage.
No matter what, the competition should be exciting, even though so many skaters have dropped out, which speaks to the depth in the men's field.
