It was a great fight. I personally had Tarver winning 7 rounds to 5, but I could see how one could have scored it for Johnson.
Tarver landed the cleaner and harder shots, but Johnson kept walking right through them and was the agressor throughout the fight.
I guess the judges favoured Johnson because of his level of activity and ring generalship.
I'm sure this fight warrants a rematch, as it was so close and Johnson said he'd have no problem whatsoever giving Tarver another shot at him.
