I think the red was a bit harsh but obviously its a poor decision from Dunk and he knew it immediatly. Shit happens though, better defenders than him have made worse decisions than that over the years. Forget and move on.
Not sure how you see that as harsh. I saw as a straight red. Last man. Goal scoring opportunity. As soon as it happened I thought it was a red, and would have been incensed if it had happened at the other end and a red wasn’t given.
