Bute is not stiff like Froch and Kessler. He is not only back and forth he also moves lateral and opens angles.
When Super 6 was put together, Froch was the most underrated of all. I did not though much of him myself. Somehow froch put it together. Froch is more proven but Bute has the far better skills.
Perfect example is Bute ko over Miranda(2:35) only that the uppercut against Miranda had a bigger distance to travel. Another example is an uppercut against Zuniga(1:17) [ame]http://www.youtube.com/watch?v=8QAAay1_-CE[/ame]
