Christopher Potter: Think a draw or a point win either way. Certainly playing at home a big help to Cavan
Brady: The abuse won't change because it's win at all costs now more than ever.
Lisa McNulty: What an inspiration Oisín McConville is. We know his story and my goodness hasn't he turned his life around.

BBC Sport at Breffni ParkNo surprise that Malachy O'Rourke has made a couple of changes to his starting 15 - but no-one saw this one coming.
He's chosen the unknown Shane Carey to make his championship debut, replacing the veteran Dick Clerkin, in midfield.
Ryan McAnespie also comes into the attack in place of Owen Duffy.
Two changes for Cavan also - top scoring forward Martin Dunne is replaced by Niall Murray, no news on whether that's tactical or if Dunne has suffered an injury.
Raymond Galligan replaces Conor Gilsenan in goals.

Monaghan have been boosted by the news that midfielder Darren Hughes is fit to play at Breffni Park today after recovering from a foot injury sustained in a club game.
Cavan defender Killian Clarke misses the big match because of a hamstring injury, but Cian Mackey is back in the Breffni line-up after missing the 2014 Championship.

Monaghan were favourites to win the Ulster before the competition started, and they certainly are on the easier looking side of the draw.
However, Donegal now have the slightly shorter odds with the bookmakers after seeing off Mickey Harte's Tyrone in last week's preliminary round.
But who do you think will be crowned provincial champions on 19 July?

Image source, Press EyeImage caption, Cavan are underdogs with Monaghan boasting a better recent record in the Championship
Welcome to our live text coverage of the first quarter-final in the 2015 Ulster Senior Football Championship.
It's a neighbourly dispute today as Monaghan travel to Breffni Park to take on deadly rivals Cavan.
A glance at the record book tells you that Cavan are by far and away the most successful county in the history of the Ulster Championship.
However, they have not lifted the Anglo-Celt Cup for 18 years and it is Monaghan who have the most recent pedigree, having won in 2013 and appearing in last year's final.
Indeed, Division One semi-finalists Monaghan are favourites to progress to a semi-final date with unfancied Fermanagh or the even more unfancied Antrim.
