Patrick Collins had to bide his time to become Cork hurling's number one - just in time for younger brother Ger to stake his own claim.
The older Collins sibling made his Cork debut in 2015 as an 18-year-old under Jimmy Barry-Murphy.
But Nash, the long-time Rebels netminder, only retired from the intercounty scene a few months ago.
Shane Kingston says it's nothing new for Pa, who at 25 is three years older than Ger, to be fighting it out for the jersey.
Kingston grinned: “I’d say they’re used to it at this stage - I don’t know what it’s like at the dinner table.
"Look, the two of them are on fire, if either one of them played (then great). They’ve been doing it since they were very young with Ballinhassig so we’re just delighted to have them there."
Pa is expected to get the nod to start in Cork's Munster SHC clash with All-Ireland champions Limerick on Saturday.
“Probably the most important player on the pitch these days is the goalie. Look, I think Pa has played five years at under-21 so he’s fairly experienced," said Kingston.
"Obviously, we were very sorry to see Nash go given he’s been so important to Cork for the last number of years but look it’s up to Pa now to take over from what Nash left at."
Kingston's father, Kieran, will of course make the final decision on team selection as Cork manager.
"It's not awkward," Shane said. "I have got used to it over the last number of years and as you can imagine he's been involved in all my teams growing up.
"It makes no difference to me. Even when he wasn't involved he was in the loop, he has a love for hurling, when he gets the chance to talk to me about it he's going to do it.
"But we try to keep the Cork stuff separate and leave it until training."
Intriguingly, although Limerick have largely bossed matters in Limerick since John Kiely came on board in September 2016, Cork there have been a number of close encounters with Cork.
“The games against Limerick over the last few years have been very competitive. Given the rivalry, each team goes out to give it their all," Kingston said.
"Limerick have backed it up in 2018 and last year. They are All-Ireland champions and we are going to have to do everything in our power to overcome them.
“Limerick are last year’s champions, they’ve won leagues, Munsters, All-Irelands the last three years so it’s a tough task.
"But we won’t be too concerned about that.
"We have to just focus on ourselves and put ourselves in the best possible position and put in a performance against Limerick and let the outcome take care of itself.
"Going into any championship game, you have to be confident. You wouldn’t be going in there otherwise."
