We beat Cork in the league this year (with what was probably the only halfway sensible team Cunningham ever put out). I do think with a full complement of players we would beat Cork. But, I don't think Cork are the best out there, as I said they might 'sneak' an All Ireland with a bit of luck going their way, but they are not the best.
I agree we struggle to beat the best of Munster, but we have beaten Limerick and Clare in the championship. On our very best day we would not beat Kilkenny or Tipp on their good days. But with the best 15 available, and maybe with the other possible exception of Galway, I do think we could beat anyone else.
