I really didn't think Kessler did enough for the 4th, either a draw or still a froch round I thought, though one of the commentators had it at level after the 6th round.
Getting a better fight, bigger punches, both saw a chance to end it in the 7th, and going for it in the 8th.
wow, what a hit Kessler took what, 12-13 seconds to go, bam.
