Agree with your whole post DP. When i rewatched it a year or two ago i was shocked by how comfortably Ray was winning this. He buzzed Benitez multiple times too. He was clearly the superior fighter.
Rewatched Leonard-Benitez. Ray controlled the action and had Wilfred in trouble on multiple occasions.
Again, I think Benitez’s most notable achievement was making Ray miss somewhat more than he had in previous fights - but that alone didn’t constitute it as being a close fight.
Ray might actually stop him. Speed kills, and Palomino was there to be hit. The only real big banger he faced was Duran, and Roberto did drop him. Hell, Muniz dropped him. Palomino is not made of stone. Leonard, in 8-10 rounds.
