Does anyone else think the Sturm/Sato fight went longer than it should have?

Why was the Felix Sturm/Koji Sato fight allowed to go as long as it did? This guy, Koji was taking a beating, man and Felix was pretty much landing at will. Am I the only one who thinks this fight went on too long? Also, I like Felix Sturm as a fighter, but why does it seem like he isn't ambitious? He seems very content to remain in Germany and no go forward in an attempt to capture the other belts in his division. I know he's gotten offers from big name fighters like Taylor, Wright, and Abraham. But he doesn't seem to be going any further. Seems like a shame for someone with as much talent as he has to not make that attempt. De La Hoya gave him some decent money. It might have changed who he NEEDS to fight in the future. Nonetheless, he needs to step up sooner rather than later or be content with being just another Sven Ottke. Nonetheless, the Sato fight was stopped fairly well. It could have been stopped a couple minutes earlier, but I don't think Sato was in THAT kind of danger.
