Yes he hasn't beaten many in the top 10 (he would have if he fought more). Yes you're only as good as your last fight (Rumble can knock out anyone in the first round). Yes MMA-math always works. DC>Rumble>Gus. That won't change the fact that Alex will stuff most takedowns. When he gets taken down he will get up. He did better in the wrestling against Jones compared to DC. In the standup Gus has far superior boxing and movement. Not sure how they compare cardio wise. There will most likely be a new LHW (paper)champ. And no, I don't bet.
