Too much focus on defensive personnel here. Personnel is not really the problem.
The goals that cost us the game against Monaghan (and many other games over the last few years) were the result of errors in concentration, and nothing to do with the defensive abilities of the men that lined out.
The first goal conceded to Monaghan was the result of poor concentration in the execution of a simple skill 100 yards from our own goal, which was then further compounded by the slow reactions of Armagh players to the dangerous situation that subsequently developed. The second goal was the result of an ill judged kick out by a rookie keeper - again, nothing to do with the ability of our defenders to defend.
These are mental failings. Failings in game management, or in-game intelligence, and they run throughout the entire team. It's a mistake to characterise this as a defensive problem - or to lament our inability to improve because 'the defenders just aren't there'. Improvements in game management, including amongst our much vaunted forward line, can and will bring about real progress.
But, clearly not enough work has been put into this area under the current leadership - we still make desperate mistakes at critical times and lose games we should be winning. All the way back to games against Galway in 2016, Tipperary in 2017, Kildare & Clare in 2019, through to Donegal and Monaghan this season.
This inability to make good on field decisions and to manage games to a successful conclusion has been a defining feature of McGeeney's reign - bizarrely, since the man himself was a master of this during his own playing days. I would've preferred a fresh voice coming in to work with this team, hoping that new ideas and new ways of thinking about the game might tighten up the psychological frailties. But we're sticking with the current man, and that's ok - maybe the nut will be cracked at the eighth time of asking. Maybe we can finally cut out the self sabotage and live out this team's full potential - the truest measure of any management effort.
