RTÉ GAA analyst Oisin McConville believes that Cork's victory over Kerry yesterday has opened up one side of the All-Ireland football championship.
The Rebels ambushed the Kingdom at Páirc Uí Chaoimh to book their place in the Munster SFC final against Tipperary in two weeks.
For McConville, who won an All-Ireland with Armagh in 2002, there is now a great chance for one of the outsiders to get to the final next month.
"Obviously there's still a blue cloud hanging over the championship with everybody looking to Dublin," he said on RTÉ's Morning Ireland.
"On the other side of the draw we're going to have a finalist from Mayo, Galway, Tipperary or Cork.
"For all those teams they must sit up this morning and think, 'what an opportunity we have to get to a final' in what has obviously been a strange year.
"There is a serious opportunity now for those counties to get to that final."
Looking back on Cork's victory yesterday, McConville said it was no fluke and that Ronan McCarthy's side will be favourites in the provincial decider against Tipperary.
Asked if they were a team that can have a run in the championship he continued: "They definitely are. There was a definite change about Cork that we saw yesterday. They were willing to fight and scrap for absolutely everything.
"They probably needed that slice of luck towards the end of the game, but using luck (to explain the win) would be unkind to them because on the balance of play, with everything that went on, they probably deserved it in the end.
"What a result for Ronan McCarthy and his team. You have to say this has to be one of the shocks of the last 10 years.
"A lot of people said that Cork were moving in the right direction, but there was a distinct possibility that they would come up short against Kerry - but they didn't. It's seismic.
"They have power. They have athleticism. The biggest thing for Cork now is to back it up and win a Munster championship.
"I think that's the game a lot of people will be looking at now. That's the big test for them now; can they put two games back to back?
"You have to say, on the viewing we saw yesterday, that that is a distinct possibility."
