Upsher looks like he was told in between rounds you are suppose to lose what are you doing. Dude just stopped trying, if he could box for a full round he'd probably win.
I thought maybe he suddenly gassed. Berto has terrible d, is headhunting and flatfooted. Looked like he got buzzed by a couple shots too.
This guy just doesn't want to be there, just told his corner he didn't want to throw and get counterd. Sad thing is when he does work he does good work because berto does have bad defense.
The guy is 30 years old. He has been in loads of wars (dating back to his early days a pro even). He's had two majour injuries in the past two years. And he came into this fight having lost 3 of his last 4 bouts and having been KOed by a journeymen. I only saw the last round so I dont know everything that you are basing that statement off of. But I've considered him a shot fighter for quite sometime now.
