Sehwag, Gambhir and Zaheer Khan were handed a lifeline as they were included in the India 'A' squad for two four-day games against West Indies 'A' later this month, while Yuvraj Singh was also given a chance to force his way back into ODI team after being named captain for limited-overs series.
Dravid said they should utilise the opportunity to impress upon the selectors.
"It is a good chance for them to get back into the national team. They have the advantage from others because
"All of them Sehwag, Zaheer, Gambhir and Yuvraj are trying hard at every opportunity they are getting. Gambhir is playing county cricket and I hope Sehwag, Zaheer and Yuvraj get some pre-season games and they do well and push the selectors," he told a television channel.
Dravid also feels that the controversial Decision Review System can get better with advancement in technology.
"You can better in every aspect of life if you try. So I think DRS also can get better. It's more of a hit and trial and you can try and improve upon the system.
"If you keep on improving the technology, say improvement in technology in the TV camera and more number of frames per second, I guess the system can improve," Dravid said.
