I don't know a thing about boxing. I use boxrec for facts, especially for dates and timelines. I try to watch as much boxing as I can in a week ESPN2, Vs. Telemundo, Telefutura, HBO, Showtime, Fox Sports, TyC streams, ARD streams, Sky streams, etc. etc. I have trained a bit and sparred a bit at a few local gyms. I don't know any pros.
