There's the pressure of Croke Park and coming accustomed to this pitch. And even last night I was amazed, shooting into Hill 16, there's always a bit of a breeze, even when you think there's no breeze in Croke Park. The amount of shots that fell short at the Hill 16 end last night from players that have played there before.
It's one thing kicking points from distance when you're under no pressure and there's nobody near you but when you have someone there right on your foot, it's off-putting and that's what Louth have been really good at - the pressure that they have applied as a unit.

BBC Sport NI at Croke Park
After a seismic Galway win that could be heard as far as Glastonbury yesterday, Donegal, Louth, Derry and Kerry have a near-impossible act to follow.
The Derry and Donegal ones had infiltrated Jones' Road early doors today. Avoiding the logjam on the roads was an obvious factor for Donegal fans, sure, but there is also just a real sense of excitement around their team at the moment.
Louth are not to be discounted, of course, but Jim McGuinness' side are hot favourites to reach the All-Ireland semi-finals for the first time since 2014.
Derry and Kerry will be huge later but today's opener should prove a fascinating battle, too.
The Armagh players delivered for Kieran McGeeney as they broke their All-Ireland quarter-final hoodoo on an emotional day for their manager at Croke Park.
McGeeney's uncle, Peter Kelly, passed away on the eve of the county's win over Roscommon on Saturday afternoon, with a minute's silence observed prior to throw-in.
Speaking to reporters after Armagh reached the last four for the first time in 19 years, McGeeney said emotions were still "a bit raw".
"Mum and dad didn’t tell me until this morning,” said an emotional McGeeney.

Donegal v Louth (13:15 BST)
Donegal selector Colm McFadden speaking to RTE Sport before the match:
"Louth's a good side. They've big size all over the field, they're comfortable on the ball. We played them in the league and they caused a lot of bother.
"They kicked 15 points that day in tricky conditions, so we know what to expect and we're going to have to be on our 'A game' today to live with them."
Galway boss Padraic Joyce praised his "absolutely outstanding" players after they responded to being "written off" by stunning holders Dublin and blowing the race for the All-Ireland title wide open.
The Connacht champions produced a stirring comeback win to beat the Dubs 0-17 to 0-16 in a pulsating quarter-final at Croke Park.
The Tribesmen trailed by four at half-time but staged a hugely impressive fightback to claim a first championship win over the Dubs in 90 years.

Barry McCambridge says reaching a first All-Ireland semi-final since 2005 means "everything" to Armagh.
Armagh defeated Roscommon by 2-12 to 0-12 to reach their first last-four tie in 19 years.
McCambridge and Conor Turbitt netted against Roscommon, who were reduced to 14 men in the first half after Ruaidhri Fallon's red card.
"It means everything to our team, the fans, the management, everyone," McCambridge told GAAGO after the win.

Donegal v Louth (13:15 BST)
All-Ireland winning captain Michael Murphy says Donegal will be taking it one match at a time but will have belief they can lift the Sam Maguire.
Donegal will be heavy favourites to reach the semi-finals after being drawn with Louth in the last eight.
After winning the Ulster Championship and earning promotion back to Division One, it has been a remarkable first season for Donegal under the returning Jim McGuinness.

Just a reminder that the draw for the semi-finals will take place this evening only if it is required.
Given the desire to avoid repeat pairings, essentially that means only if Louth overcome Donegal in our first game.
Should Donegal and Kerry win today, as Armagh have played both Galway and Donegal, the semi-finals would be Armagh v Kerry and Donegal v Galway.
Should Donegal and Derry win, as all teams would have played each other apart from Galway and Donegal, the semi-finals would be Donegal v Galway and Armagh v Derry.
If Louth and Kerry win, it'll be Galway v Louth/Kerry and Armagh v Louth/Kerry.
If Louth and Derry advance, it'll be all four teams in the hat and an open draw.
That's all for later, though. Back to the matters at hand...
Donegal v Louth (13:15 BST)
The shock of the All-Ireland champions Dublin being sent packing from the championship yesterday will serve to focus the minds of all of the favourites at GAA headquarters today.
Donegal are arguably the heaviest favourites of the weekend against a Louth side that are competing in the quarter-finals for the first ever since their inception on 2001.
But the 'Wee County' are here on merit after a last gasp Sam Mulroy free exactly one week ago sent Cork packing of course, the Rebels are the only side to have beaten Donegal in this years championship.
Ger Brennan who has enjoyed an impressive debut season in charge can once again call upon Mulroy backed by the Ciaran Keenan at centre-forward and formidable midfield pair of Tommy Durnin and Bevan Duffy.
The Ulster champions are hoping to reach the All-Ireland semi-finals for the first time since 2014 and look primed to do so on paper.
Peadar Mogan has been enjoying the form of his life this summer and looks a certainty for an All-Star should that form run deeper into July.
Daire O Baoil has been in free-scoring form as have the formidable inside forward pairing of Oisin Gallen and captain Patrick McBrearty.
There is one late change for Donegal with Conor O'Donnell replacing Mark Curran.
Louth call in Ciaran Murphy and Leonard Grey with Conor Early and Ciaran Byrne dropping out.
Donegal: Shaun Patton; Conor O'Donnell, Brendan McCole, Eoghan Ban Gallagher; Ryan McHugh, Caolan McGonagle, Peadar Mogan; Ciaran Moore, Michael Langan; Shane O'Donnell, Ciaran Thompson, Daire O Baoil; Patrick McBrearty, Oisin Gallen, Niall O'Donnell.
Subs: Gavin Mulreany, Caolan McColgan, Stephen McMenamin, Odhran Doherty, Mark Curran, Jeaic Mac Ceallbhui, Jason McGee, Hugh McFadden, Jamie Brennan, Aaron Doherty, Charles McGuinness.
Louth: Niall McDonnell; Donal McKenny, Dermot Campbell, Dan Corcoran; Conall McKeever, Anthony Williams, Craig Lennon; Tommy Durnin, Bevan Duffy; Ciaran Murphy, Ciaran Keenan, Conor Grimes; Ryan Burns, Sam Mulroy, Leonard Grey.
Subs: Craig Lynch, Chris O'Neill, Peter McStravick, Liam Jackson, Dylan McKeown, Conor Early, Sean Marry, Ciaran Byrne, Tadhg McDonnell, Paul Matthews, Tom Jackson.
Referee: Joe McQuillan (Cavan).
Good afternoon and welcome to our coverage of today's two All-Ireland quarter-finals at Croke Park.
Who will join Armagh and Galway in the semi-finals?
First up, with a throw-in of 13.15 BST, Donegal face Louth with the Ulster champions out to continue their resurgent season.
But Jim McGuiness' side won't be looking past a Louth outfit who will be buoyed by the occasion of their first ever All-Ireland quarter-final and accounted for Cork last weekend.
At 15:15 BST, we'll have Derry going up against Kerry for the final spot in the last-four.
Mickey Harte's Allianz League winners finally ended a run of three consecutive championship defeats last weekend when overcoming Mayo on penalties.
This afternoon will be an even tougher proposition, however. After Dublin's shock exit yesterday, Kerry are the favourites to be lifting Sam come 28 July.
We will have live text commentary of both games right here.
Thanks for joining us - hope you enjoy!
