Is there a more disappointing Olympic gold medalist class than Rio? (in graduating to professional)

2016 men's gold medalists, from light fly through super heavy:

• Hasanboy Dusmatov (UZB) - now 6-0 in the pros; waited three years to debut, hasn't fought since 2023.
  
  
• Shakhobidin Zoirov (UZB) - now 5-0 in the pros; waited three years to debut, fought thrice in 2019 and zero times in 2020 or 2021, twice in 2022 and zero times since.
  
  
• Robeisy Ramírez (CUB) - now 14-3-1 in the pros.
  
  
• Robson Conceição (BRA) - now 19-3-1 in the pros.
  
  
• Fazliddin Gaibnazarov (UZB) - now 11-2 in the pros.
  
  
• Arlen López (CUB) - now 3-0 in the pros; waited six years to debut in 2022; didn't fight in 2023, once in 2024.
  
  
• Julio César La Cruz (CUB)- now 3-0 in the pros; waited six years to debut in 2022; didn't fight in 2023, once in 2024.
  
  
• Evgeny Tishchenko (RUS) - now 12-1-0-1 in the pros.
  
  
• Tony Yoka (FRA) - now 13-3 in the pros.

Woof. You also have mixed results and underwhelming activity from many of that year's silver and bronze medalists (Ivan Dychko, Murodjon Akhmadaliev, Joshua Buatsi, Bektemir Melikuziev, Misael Rodríguez, Shakhram Giyasov, Sofiane Oumiha, Daniyar Yeleussinov, Mathieu Bauderlique, Vladimir Nikitin, Nico Hernández, Artem Harutyunyan, Souleymane Cissokho, and Joe Joyce). The only ones to successfully transition and perform at a high level consistently have been bantamweight silver medalist Shakur Stevenson and super heavyweight bronze medalist Filip Hrgović.

At least in the case of the Uzbeks, they have the mitigating excuse of their national program focusing their efforts almost entirely on doing well in global amateur tourneys. For the most part they seem to consider the pros a mere afterthought.

 

Flat performances abound from this bunch, in both their initial upset (and subsequent) losses as well as many of their wins.

 

Shakur was a silver medalist (and I did mention him and Hrgović as exceptions to the overall class' lackluster efforts in the OP). My thread is about how none of the gold winners have lived up to hype.

Ramírez did obtain a belt, but hot potatoed it in his second defense and has been stopped since. 3 losses in your first seventeen bouts isn't a great look for a gold medalist. Conceição also couldn't hang onto his title, dropping it back to Foster immediately with no successful defenses. Also has 3 pro losses already, not that deep into his career.

As for the other non-golds you mentioned: Akhmadaliev did manage three defenses before being upset by Tapales, but his ring schedule since has been paltry. Joyce coming out of the Rio games was projected to do a LOT better than merely an interim championship, and I think most people back then would be surprised to learn he's 16-4 and on the verge of retirement now.

 

Biggest joke-a of all is Yoka. He didn't even deserve the gold in Rio (robbed Joyce, in fact) - and I was saying long before his recent three loss skid that he was overrated garbage and bound to go tits-up in the pros.
