I think technique wise he is better than Leben. But Leben is known for his comebacks and scored another against Akiyama. I think Akiyama had him on standing technique, and grappling. While Akiyama has a good ground game, I think he underestimated Leben's and didn't respect it, even after the multiple arm bar attempts. In addition to the fact his cardio isn't really there, I think he is also a bit small for a MW in the UFC. He should drop to WW and train in the US.
