Former All-Ireland winning captain Darran O'Sullivan thinks that Kerry were guilty of underestimating Cork for granted and that they failed to adapt when their game plan wasn't working.
The 2019 All-Ireland runners-up were beaten in Munster for the first time in eight years yesterday, a goal from Aussie Rules exile Mark Keane sealing a shock victory for the Rebels in the last seconds of extra-time.
There is no back door and the team that were seen as Dublin's likeliest challengers for Sam Maguire will now be kicking their heels until next year.
"The pressure that they maybe felt, or the lack of pressure on Cork, definitely told," the four-time Sam Maguire winning forward told RTÉ 2fm's Game On.
"People have been talking about how defensive Kerry were, the setup, and the personnel they had in certain positions. That's always going to be up for debate but I don’t think anyone could have accounted for how many of the Kerry lads played poorly or within themselves.
"It’s an awful thing to say but I think a lot of them were looking past Cork. The decision-making throughout was poor and that’s all down to concentration, mentality.
"Going into they must have known the conditions weren’t going to be great, that Cork had nothing to lose. They weren’t going to let them play."

O'Sullivan was also critical of the decision to stick with a counter-attacking style despite Cork matching, and ultimately nullifying that.
"You play to win or you play not to lose and that was very evident, which is a pity," he said.
"The most disappointing thing was that Kerry had a plan A. It wasn’t working, where was Plan B?
"None of the changes were positive. Killian Spillane made a good impact but I would have preferred to see him coming on for a defensive player (rather than Tony Brosnan).
"Cork brought on Luke Connolly and Keane. They were going for it. They had one chance, to go hard or go home. They stuck with it and got their reward because Kerry couldn’t put them away.
"Cork came ready for a fight and Kerry turned up wanting to play the football that they thought they would be allowed to play.
"The Cork attitude from the first moment was top-quality. They kept going and stuck to their guns."
O'Sullivan believes that going from league champions to a Munster semi-final exit in the space of two weeks will be even tougher for the players to process, given the Covid-19 restrictions in place.
"They can’t go and concentrate on club football for a while, they can’t socialise, they’re just going to be stuck replaying that game and the amount of mistakes that they made."
