Cork captain Seamus Harnedy has revealed that the squad is playing its part in their success this year so far.
The Rebels successfully defended their Munster title last weekend when they beat Clare in the decider for the second consecutive season.
They now progress to the All-Ireland semi-final, which they reached last year, only to lose to Waterford, having come through Munster unbeaten.
But, Harnedy feels that the strength of their squad is having a telling factor on this year's new look campaign that saw them play five games to retain their title.
Cork's substitutes have made a big impression in their games to date and Harnedy admitted to the Clare Champion that competition for places is driving everyone on.
"The good thing was the strength and depth of the squad," said Harnedy. "Lads came on and made a huge difference for us. It was an exhilarating game."
He added: "We have to focus on ourselves and try and improve every day and that's all we have been doing. Training hard. You can't listen to it too much. If you do, it will eat you up.
"Lads looked inside themselves and they have done that, and the lads that have come in over the last year or two have made a difference. The strength and depth of the squad really showed towards the end when the other side was coming under pressure. Our subs were making an impact."
