The Wilder fight wasn't fixed - his opponent was scared. There are a couple of old Tyson fights that end with suspect knockouts like that one, too. It's outright silly to think Canelo-Angulo was fixed, though. Angulo just really is that slow, and Canelo really is that good. The juxtaposition of their respective styles exaggerated Angulo's shortcomings, but the man is a warrior. The promoters knew this, and that's why he was picked for Canelo's comeback following the Mayweather loss.
