Say what you will about Pacman, but win or lose the guy always fought with conviction in every fight I've seen him in. Question anything else about him, but not the man's offense. We're talking offense here, not limited to greatest punchers or atg's, like some here are getting confused about. There were many great offensive fighters that just fell short of being atgs, but still had a great offense. Meldrick Taylor, Jermaine Taylor, Arturo Gatti, Naseem Named, Ike Ibeabuchi, Jose Luis Lopez, Terry Norris, Like Quartey were some that fell short of being atgs, but on their best nights had great offensive highlight reels as great as any. Kid Gavilan and Michael Carbajal are atgs haven't seen been mentioned yet, great offensive fighters too.
Some other fighters not mentioned: Eder Jofre Carlos Zarate Orlando Canizales Dwight Qawi Jeff Fenech Jung Koo Chang
