Aldo was one-punched. Not much of an argument for a fix there.
Mendes was off the couch in a short notice fight and was doing well until he gassed, and then he got dropped and finished. Would have loved to see a full-camp rematch based on the first round.
Eddie always had a weak chin, but good recovery. But getting dropped, what, 4 times? Eventually you're just not going to recover.
The Cerrone fight is the only one on the list that actually looks fishy, but I'm more inclined to believe that Cerrone took an early out against a guy we all knew he would lose to anyway than to believe he got paid to throw a fight.
