Ó Sé ready to spring an earlier return
"And I like the bit of freshness that's there, the different voice, and all that. There is a good spirit at training, and we're feeling good.
"Look, last Sunday was very disappointing, there's no doubt about that. But at the same time it's still very early in the year, players are working very hard, and the feeling is we are going to get better.
"So we wouldn't be reading too deeply into that result. Not scoring in the second half, now that is something we can't be happy about, and again, the players know they'll have to work a lot harder on Sunday."
Whether he actually features against Dublin, either from the bench or from the start, Ó Sé is not viewing Sunday's game as some sort of make or break scenario for Kerry, nor does he even think last Sunday was just some sort or blip.
"No, I wouldn't really call it a blip. Look, we've been here before, and I wouldn't be getting too bogged down by the result.
"The reality is we are down eight or nine bodies, and I think training-wise and preparation-wise we are where we want to be, and are working hard on our fitness. So I would be losing sleep just yet.
"The problem is we do have some very big games coming up, not just against Dublin, but then away to Kildare, and Donegal, and then away again at the end of it all against Tyrone, who are looking good again too. So there's going to be no such thing as an easy game from here on, and that's something we have to be aware of too.
"It's going to be tough, but I still we have the experience to get us through."
Kerry are still without Paul Galvin, Declan O'Sullivan, Kieran Donaghy, and the Dr Crokes players, but there's still nothing like the sight of the Dublin jersey to bring out the best in whatever Kerry players do take to the field.
"Ah, yeah, there is still something magical about Kerry playing Dublin," says Ó Sé, with a smile. "It's always been there, and I still feel it anyway.
"Dublin are going well, very well, seem to be getting a lot out of the players, and bringing players through, so this one is going to be very tough."
