I still think Aldo beats every LW on the roster, nothing in the div points to a change of opinion. The guys to give him the most trouble are good strikers like Pettis, Nate and Cowboy, like a guy with less power, Hominick, showed.
He's too fast and accurate for Bendo's wild style, that flying stuff doesn't work on Aldo. His TDD is arguably the best in the UFC (right behind Jones and DC), and he's fought plenty of wrestlers who couldn't impose that wrestling on him, but got beat up on the feet.
It would be more competitive than the Edgar fight, mainly because of Bendo's strength, cardio and power GnP if he gets him down, but I don't see Bendo holding him down unless Aldo gasses. And he's too good on the feet.
