I can see some of what Wifi is getting at, DC gets worse singling out than any other player I can think of, some of which you could say he brought on himself, but most of which is due to him being our most talented player.
Therefore only he can decide how to deal with it, as nobody else has to deal with what he does, to be fair. And it's not just face-screaming, or balls being kicked away or physical tackles, it's the holding, dragging, molesting basically to stop him moving, and prevent him getting the ball, and which is allowed go unchecked to a large extent. And on top of that he rarely gets any good press to back him up or encourage him.
In some ways I could fully understand if he decided to just give it up. What's the point in trying to play when you can be constantly stopped and abused like this? It's gone over the line even though yes it's true the physicality of Gaelic football remains a huge factor for all players. I also can't see any change coming because if anything at this stage of his career he is only going to get more rattled more often. Sad but true.
