Not really all that was less than required in the team performance though Irish. With all due respect, making one player's mistake the reason for the loss is scapegoating, although from your usual posts I doubt that is your intention.
But then, making players scapegoats is a pet peeve of mine simply because expecting players to be brave you have to accept that achieves more positive play but mistakes are inevitably possible too. No player wants to let people down, team mates, fans, and himself.
