I just dont see how Ouma wins this fight. The size is such a big factor, and even if they were the same size, Ouma is all offense. He just beats down opponents by throwing 2093842 punches a round. That shit doesnt work against a fighter with a jab like Taylor's, and I've seen no evidence that Ouma is able to adjust his fighting style to his opponent. I'd say Taylor by TKO around rd 5-6.
The Wright/Quartey fight is hard for me to call because I fucking HATE Winky, so its hard for me to be objective. I think age will be the biggest difference in this fight though. Wright should box his way to a UD.
