Seriously. Do people not realize that jaw strength really doesn't get better just because you're bigger. If a guy like Dodson can KO little dudes, he can KO big dudes too, especially guys that aren't used to getting hit and will just turtle up as soon as they're punched. My brother is 5'8 (not really, more like 5'7) and when he was younger was probably 175 lb soaking wet, and a little chubby. He beat the shit out of this huge dude in Wisconsin. Guy was 6'3 or 6'4 and swung at him. By brother ducked under and blasted they guy about 8 or 9 times before the guy could react and knocked him the f*ck out. People like to pretend size matters but there are advantages to being smaller in a fight that people don't think about (smaller target and generally faster). I'm not saying Dillashaw could beat up Cain, but he could easily jack up anybody that size that doesn't train or only trains for funzies.
