It's fine to have a great defense, it is not if you are afraid to engage

This is the problem US fighters currently have, most of them are genuinely afraid to take a punch. Say what you will about IV but he wasn't afraid to take a punch, he engaged when situation required. Except Wilder and Ward the current crop of US fighters want to use IV's bicycle with Slappy Joe's slaps to win a fight. That's not how boxing works, they should all take a look at British warriors, see how things are done
