Good point re penalty RF. It reminded me of the Conor O'Grady/Marcus Hallows incident in Cork a number of years back. It was a crazy situation and should not happen at this level of football.
As I saw it Foy and Faz tussled for the ball with Foy getting it. Hughes then took it from Foy and gave it to Faz who then gave it back to Foy. As you said Faz did not celebrate the goal and did not go near Foy after he scored. I would also agree with you that Faz's performance deteriorated after this
On a positive note I felt it was a very good display with most playing well and all giving 100%. We could have won more easily with plenty of chances created.
