Funnily enough..I think old Charlo with Ronnie Shields would lose to Hurd.
People make the mistake with pressure fighters with leaky defenses that I ALWAYS See.
Their head is so easy to hit, you ignore the body, and while you hit them..you never discourage or take the winds out of their sails. I think Charlo's new trainer will key in on that and I think Charlo hits hard enough to have Hurd not jump all over him.
This is a tough one to call, I don't like Hurd's style vs Charlo's but at the same time he has fought/beaten the better competition recently.
Hurd does have a win over Harrison who has identical physicals to Charlo and maybe as much power, that does count for something.
50/50 fight, Hurd gets hit a lot and Charlo will be the biggest puncher he's fought. Charlo isn't too hard to out box or hit either, this is a match up of who's more physically gifted.
