Haney's movement is making Ramirez more desperate. Haney walked him into a good right hand with about a minute to go in the fourth round.
Haney spent much of the fifth barely engaging. Any time Ramirez got close enough to throw, Haney moved again and made Ramirez reset. There's so little action that when Haney throws a punch or two, Jim Lampley will comment on it being a "good right hand." Haney isn't deterring Ramirez. He isn't punishing him. He's mostly negating him.
