Boxing 1-2( shiva thapa or vikash krishan; May be both; they were in their teens in 2012; now quite experienced they are)
Wrestling 1-2 ( all are capable, expecting 1 medal from the girls this time)
Hockey 1 ( after so many years dreaming for a medal from men's team, #5 in world ranking now. No chance for women team)
Archery 1 (like boxers , our best hope Deepika Kumari is also more experienced now, remember she was ranked world no one before London Olympic, she was only 17 then)
Badminton 1 ( Saina, Sindhu, Srikanth- at least one of them will reach to podium, don't have much faith on doubles pair)
Shooting 2-3 ( most of the shooters have records of doing well in international events, at least 2-3 of them should make podium finish on law of average)
Atheletics 1 ( some of them surprised us by stunning performance recently, men 4x400 relay team, Ankit Sharma in long jump, maheswari in triple jump, though reaching final will be a great achievement- my bet will be Ankit Sharma )
Weightlifting 1 ( Mirabai Chanu, what he lifted in trial for Rio would have earned a medal in London; things are bit tough for Satish Sivalingam though)
Gymnastic 1 ( sounds crazy but Deepa Karmakar can make it to podium in individual vault event. Though quite ordinary in other three streams of artistic gymnastic, she is already in limelight in vault, being the third woman to successfully execute produnova vault , which has highest difficulty level. She ended up fifth in individual vault in world gymnastic championship last year)
So my prediction 10-14
