Healthiest and least healthy divisions at the moment

[codfather]

Just focusing on sporting legitimacy and ignoring commercial and entertainment value.

Healthiest:
1. Welterweight
2. Middleweight
3. Lightweight

Least healthy:
1. Super Welterweight
2. Super Lightweight
3. Bantamweight

legitimacy if you ask: heavyweight period
You could argue about CW and LHW to a degree.

commercial and entertainment value: MW WW and LW

 

[DeJulez]

WW and HW are the two best divisions in boxing right now.
