Not to forget, the drama that chased wrestler Narsingh Yadav ever since he was selected ahead of double Olympic-medallist Sushil Kumar. Narsingh was caught in the dope storm as well but managed to clear his name after convincing NADA that he was victim of conspiracy and sabotage.
On the first day of competitions on Saturday, India can eye a medal from Jitu Rai, the pint-sized star whose pistol has been shooting medals at almost every event he has participated in.
Jitu is the reigning 50m air pistol champion at the ISSF World Cup and the favourite to repeat Abhinav Bindra's gold medal feat of Beijing 2008.
Currently ranked 3rd in both 50m pistol and 10m air pistol, the 28-year-old has won two golds, three silvers and one bronze in the World Cups, an Asian and Commonwealth gold and besides an Asian Games gold.
In his fifth and final appearance, Abhinav Bindra, who would be India's flag-bearer at tomorrow's opening ceremony, would look to end his career on a high even though he has not been in his top form.
Bindra will be joined by London Olympics bronze-medallist Gagan Narang, who will compete in three events, in his fourth appearance.
Focus will also be on the likes of Heena Sidhu, Ayonika Paul, Apurvi Chandela -- the three women shooters.

Inside the boxing ring, a squad of three will carry India's hopes. For a discipline, that had a record eight entries in 2012, this time it will be under-represented with three men in the ring.
Then there's the senior-most member of the team, Manoj Kumar (64kg), the 2010 Commonwealth Games champion who will be the dark-horse.
Having failed to live up to the hype four years ago, the Indian archers have arrived about 15 days early to acclimatise themselves as they hope to make their mark by clinching at least one medal in the women's team event.
The experience of L Bombayla Devi, who is competing in her third Olympics, along with the talented former world number one Deepika Kumari and promising Laxmirani Majhi make them a potent force among the Koreans, Mexicans and Italians.
Athens bronze-medallist Paes would aim for his dream doubles Olympic medal in his seventh straight Games -- a record for any tennis player.
But it is the duo of Bopanna and Sania Mirza in the mixed doubles where India have a better medal chance as they can complement their game styles to match each other's abilities.
Badminton too is seen as a medal prospect for India where London bronze-medallist Saina Nehwal and the promising PV Sindhu, who won two World Championship bronze medals in 2013 and 2014.
Her Australia Open Super Series win in June has put her in right stead but it's Sindhu who may be the dark-horse.
Gymnastics also holds some promise where 22-year-old Tripura girl Dipa Karmakar became the first female gymnast from India to qualify for the quadrennial event.
