Getting inside and going to the body is not the key. That defense is not about the shoulder roll alone. It helps protect the body as well. You can't go to the Castillo fight to say that is what you need to do bc Floyd wasn't even as good defensively back then as he is today with the philly shell and I don't recall him using it much in that fight. He just gave tons of movement. Corley caught him with a good shot and so did Judah but that was at mid range. Going to be hard as hell to break that Defense on the inside. I just think it will take a much bigger fighter with a great jab who can come over the top of that shoulder with a right hand, but you have to time it just right. If the timing is off you are going to catch the shoulder and extend off missing his head.
