Took an inventory of TBRB's divisional rankings from 115 - Heavyweight to see how promoter affiliation may influence the rankings and to see how well each of the "BIG 4" were represented.

Results -

PBC - 40 (different boxers)
MR - 27
TR - 24
GBP - 11
N/A - 38

(1/4)

The results suggest TBRB doesn't have promotional bias when coming up with their results.

There's a lot of talent out there (38 boxers) that could use a major affiliation. Particularly, Cruiserweight where there are 8/10 guys without a major push.
