I'm going to be rooting for Adamek but based on the two styles, Cunningham might have the slight edge here. He is the better boxer, is natural at cruiser weight and has decent punch. If he fights the way he fought Huck, then i can definitely see Adamek winning because brawling is his kind of fights. Cunningham would need to utilize his jab and control distance.
Adamek UD. Not having to worry about Steve lack of power will allow Adamek to unleash constant combo's. The difference here...Adamek's instinct when hit is to immeditaly come back with something of his own,Steve when hit clean either clinches or runs.
