Keith Thurman's the harder puncher and has better defense (Chaves, Zaveck, Lora, Quintana) landed just 29% of their power punches. Soto Karass is on a roll (wins over Aydin & Berto) and will bring the heat vs. Thurman. Karass avg'd 98 punches thrown in his last 4 fights, landing a respectable 35% of his power shots. Karass' opponents landed 48% of their power shots. Thurman's jab is under rated. He'll need that to hold off the hard charging Karass, who will be fueled by San Antonio fans.
