A thread 🧵
1/8

Tasty ones coming up ✊ 🏐

Which is people’s pick of the round?

Mine would be
- Louth v Armagh Round 2A
(will get a proper sense of where Louth are now)

- Derry v Meath Round 2B
(Could be a war of attrition up in Celtic Park)

I’m loving the new All-Ireland format

[Ciaran Deely PhD @CiDeely]

Some nice new research here below from @DrDavidNolan @behan_s & especially @tmolohan ⬇️

[Ciaran Deely PhD @CiDeely]

@1989_scooter Yeah although Derry at home v meath and Monaghan at home v Roscommon might be tricky for the away teams 🤷‍♂️

You’re right, harder to call 2A
Especially as you get a second chance if you lose
Changes the dynamic slightly

[Ciaran Deely PhD @CiDeely]

Round 2A teams:
- Win and you’re into a 1/4 final
- Lose & you’ve another bite at the cherry against Round 2B winners

All-Ireland SFC round 2A
Donegal v Cork
Galway v Westmeath
Tyrone v Mayo
Louth v Armagh

———-
Round 2B teams:
- win & you’ve a play off to reach the 1/4 Finals v losers of Round 2A
- ⁠lose & it’s time to put the feet up, follow the World Cup in North America 🌍 and binge-watch Love Island ❤️🏝️

All-Ireland SFC round 2B
Derry v Meath
Kildare v Kerry
Cavan v Dublin
Monaghan v Roscommon

@1mgfc @KillerMcHugh @DeelySport @markdeely @RIVERSIDEBOY79 @BarryMullane1 @brendand_8 What scientific progress?

And if you’re watching it for free, why would you pay for it?

[Ciaran Deely PhD @CiDeely]

@KillerMcHugh @DeelySport @markdeely @RIVERSIDEBOY79 @BarryMullane1 @brendand_8 Absolutely 💯
And that’s why you can’t have any hard and fast rules that work all the time

You want your team and players to be tactically flexible
And decide things on the fly (based on sound principles of defending) at all moments of the game

[Ciaran Deely PhD @CiDeely]

Think a lot of people in the comments are missing out on the point here

Obviously 16k in Croker is more than the ~7k allowed in Parnell Park

But a full (small) county ground is a WORLD AWAY from a 20% full Croker.
It’s empty, no other way of describing it

And for the good of Dublin themselves (see result!) the team and support would be much better off in their proper home ground

(Obviously it’s a side point that the capital probably should have a 25k seater for Dublin’s (and other games) use

Do you need to choose between man-marking and zonal defending? 🏐

Ciaran Deely @CiDeely explains how a hybrid defensive approach can help you nullify the opposition’s key threats while maintaining a strong, organised defensive structure across the rest of the pitch.

The best of both worlds: targeted pressure and collective control.

[Ciaran Deely PhD @CiDeely]

@KillerMcHugh @DeelySport @markdeely @RIVERSIDEBOY79 @BarryMullane1 @brendand_8 Yeah exactly John
The defending team needs to identify when they actually need to mark the opposition player versus when the opposition player’s movement is only being used as a decoy runner to disrupt a balanced defence

[Ciaran Deely PhD @CiDeely]

@IndoSport @PhillyMcMahon 😂😂😂 ah now, come on lads

Is this really the analysis on how to stop
David Clifford?

🏟️ Croke Park finals are massive for Christy Ring, Rackard & Meagher teams — giving players from developing counties the chance to perform on the biggest stage in hurling. A huge occasion for players, supporters & the growth of the game 👏

[DSS Coaching @DeelySport]

Coaches: a good zonal defence doesn’t have to be complicated 🏐

Ciaran Deely @CiDeely outlines a balanced zonal defensive structure and explains why it can be so effective in Gaelic football — protecting space, supporting teammates, and reducing exposure in 1v1 situations.

Simple principles. Collective movement. Better control without the ball.

[Ciaran Deely PhD @CiDeely]

@Jamesscott89Com Congrats James and best of luck for the future in this 🇮🇪 ✊⚽️
