First and foremost, i think Eubank Jr. Is an overrated , disrespectful, deluded Cock! He doesn't possess that much skill, is raw, tries to make every punch a knockout punch by loading up ridiculously, and as proved in the first 6 rounds against Saunders, doesn't have a great Boxing brain.
However, he looks and sounds more composed and rational when his Dad isn't around. If he's anywhere near as good as he or other people are trying to make him out to be, He will win this fight very easily. He dwarfs O'Sullivan, who himself has a bit of a Bar room Brawler style, and i can't see getting anywhere near him. One thing Eubank Jr. Does possess is good conditioning and stamina.
Easy fight for Eubank Jr. That doesn't prove a lot to me.
