Best at creating great punching angles?

Juan Manuel Marquez. One of the best at creating the perfect angles and amount of room needed to let his combos flow.

 

I'd also add Jiro Watanabe, Alfonso Lopez, Chan Hee Park, Hillario Zapata, Yoko Gushikien and of course maestro Miguel Canto.

Then you have the obvious like Duran, Canizales, Loma, Pac etc.

Joichiro Tatsuyoshi and Hozumi Hasegawa were also very adept at offensive angling, particularly Hozumi, but their defense could be questionable, especially Hozumi's. I'd also add in Harada, who was almost frantic at times, and compare him to the mechanical effectiveness of Jofre. Hell, even action fighters like Katsyu Onizuka had good angling offensively (he's similar to Arguello IMO).

Steele was awesome with angling, like a classic style mixed with Ukrainian, and a bit his own instincts. Giardello was almost bebop in his own angles too.

 

Michael Spinks did that at heavyweight, though the punches were typically powered by his weight-lifting arms and not his body.

Had Michael had a significantly better shot he conceivably might have beaten Mike...

wait a minute, nahhhhh.
