Degale will never , ever be able to take Bute out in 4. Remember how much hurt had Froch put onto Bute to be able to take him out on his feet. Bute's chin is not that bad, not iron either but just not as bad as some say or want to believe it is. The problem with Bute is his defense and lack of close range solutions. His new trainer, Grant has stated this himself. That Bute could fight very good at long and middle range but when a fighter got past that he didn't knew what to do. So he tried to teach him a bit of inside fighting. We'll see if he had a semi-success with this, because nobody masters inside fighting so fast so late in his career, but just a little activity inside while getting out of that range could do wonders.

I do not think much of Bute as an elite champion. He is a very solid fighter, but I do think that De Gale is the better fighter and will win by 4 to 5 points on the scorecards. Something like 116-112 or 116-111.
