A missed goal at one end, an avoidable green flag at the other. Both swung momentum to Armagh. Both grew the influence of the Armagh crowd.

Jack O’Connor’s post-match analysis honed in on a third quarter where Tom O’Sullivan was presented with two green flag opportunities. With the first, he refused to take on the shot and doubled back. For the second on 41 minutes, he took the shot but the shot went wide.
