With an aim to build a strong reserve pool, India has fielded its development squad for the Azlan Shah Cup and rested six of its senior players, including regular skipper Sardar Singh.
And Nobbs said the main idea behind the decision to field an under-strength team was to prepare the youngsters for the FIH Junior World Cup to be held in India later this year.
"It is also a good opportunity to draft in some junior players as they are the future of Indian hockey. It will also create a healthy competition for places in the team.
"Mandeep's (Singh) performance in the Hockey World League is a prime example of the fact that junior players need development. Mandeep found international hockey lot tougher than Hockey India League. He has got talent but require development," he said.
Nobbs said with a long season ahead, it was also imperative to give rest to some of the already-exhausted senior players.
"The other objective behind the decision to send the development team was to give rest to some senior players, who are either exhausted or are carrying injuries, because we have a busy schedule ahead," the Australian insisted.
