Don't get me wrong, Bendo is a beast. But as far as future tests go, the other divisions don't hold a candle to LW.
Who does JDS fight after he turns Mir into a vegetable? Cain? Werdum? He already knocked both of these guys out.
How about Jones? Who does he have left after Hendo?
Or Silva after Chael?
When you watched Condit vs Diaz did you not think GSP was laughing his ass off?
Then there's Bendo.
Then there's Jose Aldo.
Then there's Cruz.
It is what it is, most of these guys have cleared out their divisions, but Bendo still has a way to go, and winning a title match is not the same as winning a series of title defenses.
