I don't think any of the guys left in the Olympics will do well.
Jacobson is US domestic level, in the modern US greco era. He is just part of the field, there to be a climb the ladder win for the medalists.
Rau is so basic. And he's old. I saw him talking about learning par terre defense, at an age when a lot of wrestlers retire. 97 kg has pretty stratified tiers. I think any of the tier 1 wrestlers should tech him and tier 2 types beat him comfortably.
Coon has the luckiest silver medal of his generation, but he has been part time greco with his failed nfl stint. It matters less at 130 kg but still. He overwhelmed with his size and strength in that dream draw run, but most of those types of people have been weeded out at the olympics. I think Semenov destroys him again if they meet. He'd need a dream draw again, be at his best form, and to wrestle someone like Alin for bronze to get a medal.
All three are low ceiling types (unlike past games with G'Angelo). It would be more exciting if there was a low floor high ceiling competitor.
