Rugby League is the best sport in the world imo. Also a big soccer, tennis and cricket fan, but for pure athleticism and brutality nothing beats rugby league.
I would say basketball, although soccer is the worlds no. ball sports but basketball player specially in the nba makes most money with excemption of David Beckham of Los Angeles Galaxy ,with basketplayers size, height and athletism, no wonder basketball is fast catching up as worlds number no.1 in sports.
I will watch almost any sport at the elite level. Olympics and World Championships. One on one competions are my favourites, in particular, Boxing, Kickboxing (K1) and Tennis.
I think many sports are horrid to watch on TV but are infinitely more interesting if you see them live, Soccer ( I would think), hockey, baseball, etc
