I hate the idea of judging the fight based on who is trying to finish the fight.
I think it is about who is controlling the fight and effectively using their skills regardless of whether it finishes the fight.
Wanderlei probably tried to finish the fight more than franklin did but franklin had better skill, technique, accuracy and strategy. He landed more punches including power shots, avoided more punches, and for the most part made the fight take place at his pace and style.
IMO, the goal of any sports competition is to win. Of course the most effective way to win is to finish your opponent. However you may not always be able to finish your opponent so rather then just wildly swinging for the fences you may need to use smart strategy and tactics that play to your strength and skillset. More and more i hear guys who are saying they would rather put on an exciting fight than win and i just cant buy into that mindset.
I guess it comes down to whether you want to view it as a sports competition or sports entertainment.
