Giles is not concerned about his side's relative inexperience, though, instead viewing it as a learning period for all concerned.
"The Test team before Christmas was full of guys who had played a lot of cricket, when you have some guys who are lacking experience you need your big guys to step up," he said.
"My job is to take this team forward and that might take time. We are going to look at different players. There are big tournaments coming up where we would hope to have our 'A team' all the time, but in between we need to look at some of the younger guys because they are our future.
"We have to look after our cricketers, particularly with the amount of cricket we have coming up.
"In the next 12-18 months it is imperative we look after our best players, both physically and mentally.
"If that means occasionally resting them or rotating them out of the side then that is the way it will be. But wherever there is injury, or rest, or rotation there is opportunity and it's up to the young guys to show what they can do."
