Kashyap had become the first Indian men badminton player to reach the quarterfinals of the Olympics in London last year and Guru said his performance instilled self-belief among his fellow shuttlers to do well at the international level.
"Men singles have always been in the limelight for Prakash (Padukone) sir and Gopi (Pullela Gopichand) sir and seniors like Arvind, Chetan and Anup. But suddenly there was a gap and no one was in the top 20. But I think it was Kashyap's performance at London Olympics that changed everything," Guru told PTI.
"It was sad that he could not win a medal at the world championship. It would have further inspired all of us to do well. But I can say that all are equal now in men's singles," added Guru, who had reached his career-best ranking of top 20 last month.
"It helps a lot to play against different players in the academy. Earlier, I used to play Kashyap and Sai Praneeth, so it was 2-3 players but now we have seven or eight different players at the centre. So the intensity is also high at the practice. It is giving us more results in the men's singles."
The 23-year-old said he was working on his strength and hoped to break into the top 15 by year end.
