It's exciting because people do think Mayo have a genuine chance of beating a Dublin that are not firing on all cylinders and I think there's a lot behind that.
We love Mayo-Dublin, it's the energy they bring. When they cross that white line, it's the hatred that's there - yes there is respect between them but they play on the edge.
I have said it numerous times, Horan has done tremendously well with Mayo. They are top of the pile in Connacht again, he gives no excuses, he drives on with it and the style of play is aggressive. We saw that in the second half against Galway.
They hammered Leitrim and they hammered Sligo, but Galway were always going to test them. In the first 33 minutes when Galway pushed up on them, really pushed up on them, Mayo only had four points. They ran at Mayo, they kicked directly and caused them trouble, kicking goals and points, but Galway could not keep it up.
A lot of people are asking did Galway collapse totally or did Mayo ramp it up in that second half?
In the second half, Eoghan McLaughlin and Kevin McLoughlin, who I expect to start tomorrow, were excellent. Mattie Ruane was outstanding.
Mayo and Dublin live on the edge. My worry for Mayo is that Dublin will pressure them like Galway did in that first half, and the mistakes that came from Mayo - the wides, the missed passes and missed tackles might happen again.
Another issue is that Tommy Conroy and Ryan O'Donoghue - there is fierce pressure on them. Cillian O'Connor is missing. Will they put Aidan O'Shea inside? He's vital to them around the middle of the field, so I'm not sure. Oisin Mullen and Paddy Durcan will be detailed to mark Ciarán Kilkenny and Con O'Callaghan. Will they attack as much?
There is an awful amount of talk about the trouble around the Dublin camp - the Cluxton issue, Eric Lowndes walking away, Kevin McManamon at the Olympics, Philly McMahon at the soccer (with Bohemians). All that talk means there is no happy camp.
Until they lose this talk is nonsense. To be fair, people saying that they don't have the pace and penetration now, that's fair enough, they haven't been going as well as they have, but why would they not go for it if they are still winning. They are still beating teams. They are not conceding big scores. John Small and Eoin Murchan are back, Cluxton has not been missed yet.
The two big players for Dublin this weekend will be Brian Fenton and Con O'Callaghan. Fenton will relish going at Mattie Ruane, O'Callaghan will be picked up by Oisin Mullen, who they say might be injured.
I expect Dublin to just about win it. I expect them to ramp it up. Mayo's Achilles has has been their forward line; I'm not sure they get enough scores. They'll need a couple of goals to get over the line here. It might not be enough still.
I expect Dublin to improve greatly. It will be a cracker. I will just about go for Dublin.
