Dublin are just something else.
When you look at Dublin you are looking at one of the greatest teams to ever grace a GAA pitch.
Just think about their achievements, 2011, 2013, 2015, 2016, 2017.
That is just ridiculous, three in a row in this day and age is something else and to do it against a superb Mayo side will only add to the legacy of the Dublin footballers.
You wonder how Dublin have got to the point where they are, there's a lot of factors. Funding and sponsorship is one, a talented crop of players is another, Jim Gavin obviously has played the biggest of roles but there's the behind the scenes of it all too.
John Costello may be the unheralded hero in all of this, the Dublin GAA CEO laid out the blueprints for Dublin's success, vast improvements in the underage structure over the years played a huge part of Dublin ending their 16-year year drought of an All-Ireland and the crop coming through only seem to be getting better and better.
Costello has played a pivotal part in Dublin GAA and football, in particular, being in the great shape that it is, it's some achievement.
And then you look at his son, Cormac. As Mayo found out in 2016 there's not an ounce of nepotism in his inclusion in the squad Cormac is extremely talented.
Three points from play he scored in the All-Ireland final replay in 2016 to get Dublin over the line, an injury-ridden 2017 prevented Costello from pushing and becoming the household name he will surely become over the years.
At just 23-years of age, Costello has four All-Ireland medals to his name and has got to share some special moments with his father after each of his successes.
Yesterday was no different.
The Whitehall Colmcille clubmen posed for a photo with Sam Maguire, something that is becoming normal for the pair now and it's hard not to be jealous.
The hard work and dedication by both men paid off and now they reap the rewards, you can only envy the position they are in.
Fair play to them.
