Dunne’s mind games aren’t helping Model prospects

Did he really think he was going to upset Dublin? Because it didn’t look like that to me, Dublin six points to one up after 12 minutes and looking like they were going to run away with the game. In fact it looked like he upset his own players and it took them a while to adapt.
What does it say to your players if you don’t have the confidence to name nearly half of them to the starting 15 before a ball is thrown in?
