He's great at winning rounds, even in 'close' fights he wins 50-45 but without power to keep the bigger guys off him I have a feeling he can get broken down rather than take fights over...No expert, but it appears Volks left hand is pushing against the right arm of Ortega which takes off a lot of the pressure and stops it from being completely locked in. If Ortega didn't cop the early damage, that's probably the fight done.
Volk's gonna be hard to dethrone. He'd make a real impact at 155 I think too.
Old adage 'we have weight classes for a reason'. That said, skill for skill I think he beats a lot of guys at lightweight and maybe moving up gives him more power, who knows. Still got good fights at 145 but stuffed if I want to see a 3rd Max fight. If that's the option, go up
