'He was all over the place' - Joe Brolly gives his verdict on the Aidan O'Shea-Kieran Donaghy duel
David Brady had suggested it during the week and Stephen Rochford did deploy Aidan O'Shea at full-back in an attempt to neutralise Kieran Donaghy's threat.
Former Kerry midfielder Mike Quirke believes the decision cost Mayo a place in the All-Ireland final.
While Donaghy contributed just one point in the 2-14 apiece draw and the expected aerial bombardment never materialised, Donaghy drifted out and was Kerry's best creative force.
Joe Brolly told The Sunday Game Facebook page that Stephen Rochford's ploy back-fired.
"It didn't work out, Donaghy was the crucial influence on the game from Kerry's perspective. They wouldn't have survived in the game without him. He set up 2-4 and scored a point," he said.
"He realised very quickly that he was no longer an aerial threat because O'Shea knew how to deal with that.
"He drifted out, he set up, he had space all the time because playing full-back is a world away from playing midfield.
"A good full-back spends a lifetime in there and understands it and you could see that Aidan O'Shea was all over the place."
Colm O'Rourke doesn't think the Connacht side will go with the same tactics next Saturday at 3pm.
"At the start we would have said, it has worked the charm but I don't think they'll repeat it next Saturday because Donaghy got much the better of the duel," he said.
"I think they'll have a new full-back the next day, they'll push Aidan O'Shea further up the field and they'll look at the Kerry kick-out because that is one area I think they can improve significantly on."
