His defence needs some work, when hes not throwing (which isn't too often) he'll stand there and just absorb the punches he needs some waist movement and also not to just stand there and trade. Too often young rising fighters stand there and trade cause they know they have the power to KO the fighters they are facing but thats not the way it's always gonna go. They are so used to blasting past opponents that once they face someone who they can't KO they become frustrated......
Juan Ma looks to have the goods with some tunning he can only become better....
