I think all virtually all fighters can be exciting or boring depending on whose in front of them, often its the matchmakers responsibility to choose boxers whose style will gel well with their opponents.

I guess watching Witter and Ruiz is painful sometimes, and I'm not really a fan of Hatton's mauling style either although it would be overly harsh to put him on the least exciting list.

Most German fighters bore the tits off me, so upright and slow most of em.
