Right now there are plenty of weak divisions. I don´t care much for what happens south of lightweight with some exceptions, so I skip these weights. Super Lightweight Super Welterweight Middleweight Supermiddleweight Lightheavyweight Cruiserweight Heavyweight all weak divsions. Thanks to those unnecessary "Super"-divisions. Very bad for the sport.
After careful inspection the weakest divisions are (in no particular order): Light Flyweight Minimumweight Flyweight Bantamweight Light Middleweight _____________ 'Honorable' mention: Heavyweight
How is 168 weak? I think you are confusing "american" with "strong". 160 is terribly shallow, far weaker than 168. Jr Middle isn't that bad if you have a good look. After Pav and AA i'd say MW is one of the most shallow. Cruiserweight obviously is pretty second rate.
Cruiserweight is not weak. Some people don't seem to realise the difference between popularity and marketablility and actual skill. There are just no names. Bantam has overtaken 154 for me. It's pretty dire.
Cruiser. They haven't been anything to watch since Hollyfield was in it, and even then he was the thing worth watchin' there.
