Angulo could use an uppercut. If he added that to his arsenal he'd be the total package. He cuts off the ring nicely, targets the body wonderfully and is strong as hell.
If I was a 154-pound fighter I'd be doing what I could to avoid Angulo.
The referee in that fight was a sadist. He did the right thing by not stopping it in the 3rd but he let it go on too long at the end.
