Silver linings and all that. Jack O’Connor hopes this 13-point defeat to Donegal, Kerry’s biggest reverse in a final in 25 years, will put paid to claims they are certain to defend their All-Ireland title.

“A game too many” was his assessment of a match where they were overrun and conceded three goals in as many minutes in the second half.
