Between League and championship, Dublin have gone twenty games unbeaten, a run which stretches back to their two-point loss in Killarney on 1 March last year.
We're confident that this is the longest unbeaten run across Gaelic football's two premier competitions at least in the past 40 years. All through Kerry's golden era in the late 70s and early 80s and again in the mid-80s, they never were never rampant in the League.
The sketchiness of the GAA's maintenance of League records online makes the exact figures difficult to ascertain.
In Dwyer's time, Kerry won three League titles, in 1976-77, 1981-82, and 1983-84. Only in the last of those years did they follow it up with an All-Ireland victory.
Kerry went unbeaten in the 1983-84 season, winning three and drawing four (oddly enough) in the League proper. They proceeded to win the quarter-final, semi-final and final to go ten games without defeat across the League campaign. Four games later they were All-Ireland champions. Fourteen games unbeaten. This is basic maths.
They followed it up with an indifferent League performance in 1984-85. They won two, drew two and lost three and failed to reach the knockout phase. Even assuming they finished with three successive losses (which it probably didn't), their unbeaten run only hits eighteen games.
Any other contenders. Meath's intense period of success in the late 80s. They won two successive All-Irelands in '87 and '88 and claimed a National League title in between these two victories.
However, they didn't go unbeaten in the course of their 1987-88 NFL win, losing just the one match en route to the title.
Of course, if you include the O'Byrne Cup, the Dubs long unbeaten record isn't so long.
