...should have been boring, and bouts that should have been exciting. Example 1: Two defensive boxers...bout should have been boring, but it was very exciting/intriguing. Example 2: Two come forward/all action boxers...bout should have been very exciting, but it didn't live up to the hype.
Haye vs Audley.....wtf? Don't boxers punch? Andrew Hartley vs Charlie Zelenoff.....the big Russian was supposed to just smash the midget hillbilly. Little Hartley wound up running him out of the ring and the sport altogether. This led to years of online trash talk. And a rematch. In which Zelenoff attacked Hartley in the dressing room before the fight and hit him while he was putting his pants on. Pants half way on, Hartley still takes his best shot. And then Zelenoff's dad beats him on camera and offers to bribe Hartley to not go to the police.
Pac Mosley is an obvious one, Shane changed his style completely in that one though. I've drawn a blank.... Hopkins-Pascal 1 was pretty entertaining for what was expected beforehand.
