we beat mayo by a point 2013 (lost the year before), they took us to a replay last year. We beat Kerry by a point 2011, and 3 points last year, and they ran us level almost to the line in 2013. Donegal beat us by 6 or 7 in 2014, we beat them by 2 in 2011. Forget Cork, and no recent games Vs Tyrone.
So since all those games, Donegal have gone back, Kerry have waned, waxed, and probably waned a bit again. Mayo are more or less the same, a little better. Dublin got better from 2011 to 2015, overall. Still had those close games last year, when most things were really going for us.
And since last year we've lost 3 of our best/most important players, and some who are nearing the end are a year older. What gives you such confidence we will still beat Kerry & Mayo? Or Donegal if they find that other gear again?
