I have already posted my prediction here, but I decided to explain a little bit more
Archery - no chances
Artistic Swimming - no chances
Athletics - as usual, not too many chances on this sport. But, I am expecting a good performance from some of our athletes.
Mens 4x100m relay, mens shot put, mens 400m hurdles and women and men race walk 20km might be good opportunities to get a medal
Badminton - no chances
Baseball - no qualified
Basketball - probqbly we will not qualify
Beach Volleyball - always a good sport for us. Getting medal since Atlanta 1996, so I am expecting at least one. The best chance is Agatha and Duda.
Boxing - Bia Ferreira is favorite on her weight ( I cant remember right now haha )
Its not impossible to get more medals with other boxers
Canoeing - for sprint Isaquias Queiroz and Erlon de Souza. Two events for Isaquias, and I am hoping for two medals and at least one gold.
Slalom is a little bit more difficult, but Ana Satila may get a good result.
Cycling BMX - although I am not expecting a medal from here, our athletes are good and falls always can happen.
Cycling MTB - Henrique Avancini, our idol! Haha
Cycling Road - No qualified
Cycling Track - No qualified
Diving - no chances
Equestrian - Maybe Marlon Zanotelli on jumping
Fencing - Nathalie is the only chance here, and I am not too much confident.
Field Hockey - no qualified
Football - always a good chance. I am expecting at least one medal. And hoping for a good result from our womens team, now with Pia Sundhage as coach.
Golf - If qualifies, no chances
Artistic Gymnastic - I am counting with two medals. Arthur Zanetti, Artur Nory, Rebeca Andrade(if she qualifies) and Flavia Saraiva are the contenders for these medals
Rhythmic Gymnastic - no chances
Trampoline Gymnastic - if our girl qualifies, no chances
Handball - looking at our last results and the groups at Olympics, quaterfinals will be awesome
Judo - awful results lately, and without Rafaela Silva our chances get smaller. Only heavy weights and maybe the team competition
Karate - Vinicius Figueira is almost qualified and he is our best contender here. Valeria Kumkzaki is closer to get a spot as well, and she had good performance and results lately, and with much lucky Douglas Brose will get a spot.
Modern Pentathlon - no chances
Rowing - no chances
Rugby Sevens - no chances
Sailing - Robert Scheidt is going to his last Olympics, and I cant doubt from a multi medalist like him. 49erx and Nacra have good chances too
Shooting - on the last minute our medalist, Felipe Wu, in Rio qualified. I have contact with him, so I am sure that he is going to do everything for another medal. But the task is harder this time
Skateboarding - the best thing for Brazil haha many chances in all events. Women Street is possible we see a podium only with Brazil.
Softball - no qualified
Sport Climbing - no qualified
Surfing - Medina and Italo, we dont expect less than a gold. For women a medal would be great
Swimming - Bruno Fratus in 50m freestyle and Ana Marcela Cunha in marathon are the best chances. Any other medal will be a surprise
Table tennis - very hard, but not impossible for Calderano
Taekwondo - three athletes, and imo, three chances. But taekwond is very unpredictable.
Tennis - Marcelo Melo and Bruno Soares for doubles is our only realistic chance
Triathlon - our girls are in a amazing shape lately. Not impossible but very hard
Volleyball - mens team as always very strong. The womens decreased a lot since Rio
Water Polo - no qualified
Weightlifting - Fernando Reis may get it in heaviest weight
Wrestling - our girls are doing great. I am still expeting Giulia Penalber qualifies in last tournament. And maybe Kamila. Very hard get a medal here though
