Bute must put the hurt on to Froch's body early on becaue Bute does tend to tire out as his fighting style is very draining. In all Honestly I think the fight will be decided in the first four rounds. Not due to a KO but because by then you'll see who came in the ring with a better plan.

That said and done I think Bute will do exactly that and slow froch to a crawl where he's reduced to pop shotting and counter punching.
