Sounds like the BB today stands for "Blood Bowl", not BuzzerBeater.
(http://www.tbbf.org/houserules.asp) (check the Handicap table... "Bribe the Ref" used to be part of the official rules, IIRC... now lives on in some house rules)
Interesting (maybe) aside... I used to play a lot of Blood Bowl on fumbbl.com, where someone mentioned Hattrick once upon a time. So I started playing HT, and my Blood Bowl interest waned. Then I learned about BuzzerBeater through HT, came here, and my HT interest went from wretched to non-existent... so if it wasn't for Blood Bowl, I wouldn't be here.
