Even this time, the freestyle contingent looks very strong and is expected to add at least 10 medals to India's overall tally.
The last two years have seen Indian wrestling scaling new heights with Sushil's second Olympic medal after Beijing, a historic silver medal at the London Olympics in 2012 and Yogeshwar's bronze at the same event.
The two will lead India's campaign in new weight categories after world body FILA dropped their respective categories in December last year while tweaking 19 other divisions.
Sushil, who won bronze in 2008 Beijing Games and silver in London in the 66kg freestyle category, has moved up to 74kg while Yogeshwar will be competing in 65kg, and not 60kg as last time.
Although the two grapplers do not figure in the world rankings as they had been on a long sabbatical after the London Olympics, they are expected to bag gold in their respective categories.
Despite their absence from the international arena, both Sushil and Yogeshwar came up with impressive performances last month in the senior international wrestling tournament in
Sassari, Italy as they fought in their new-weight divisions for the first time.
While Yogeshwar won a gold medal in the 65kg freestyle, Sushil finished with a silver medal in 74kg.
The other Indians in fray -- Amit Kumar (57kg), Bajrang Poonia (61kg), Pawan Kumar (86kg) and Satywart Kadian (97kg) -- are not affected by the change in the weight categories, and will also be looking to prove their mettle at the ongoing competition, having won many laurels at a number of international events.
In the Commonwealth Wrestling Championships in Johannesburg last year, the grapplers brought home a total of 14 medals, winning seven gold medals, four silver medals and three bronze medals along with the team title.
Both Pawan and Satywart had bagged the yellow metals during the tournament. Satywart earned a medal for the first time in the heavyweight category for India and a lot is expected of him in the 97kg division.
India would bank also on Pawan for a podium finish here.
At the World Championships in Budapest last year, 20-year-old Amit had won a silver medal while Bajrang bagged a bronze. He had also earned a bronze in the Asian championships last year.
Amit had become the youngest wrestler to represent India at the Olympic Games in London and his experience will surely count when he enters the ring here.
As far as women grapplers are concerned, they would also be keen to better their performance of the last edition, where they had clinched three gold, two silver medals and a bronze.
The experienced Babita Kumari will spearhead the Indian challenge in the women's section. She will be looking to defend her gold in 55kg freestyle category.
India will however, miss the services of Babita's sister Geeta, who had also won a gold medal in the previous edition.
Vinesh (48kg), Navjyot Kaur (69kg) and Jyoti (75kg) are other female contestants whose skills cannot be underestimated.
