I watch a lot of different kind of sports, but really zoom in one or two sport,for one year at the time their leagues and teams, doing power numbers for every team, so i can follow how correct my (and others) thought process was before seasons started.Last and this year it has been hockey and NHL for most part, and soccer comes along every year at some way, usually its one first division from som european country.
But there is snooker,tennis,basketball,nba, also kind of under my radar, those are great sports to bet,pre and live. There is certain details or cerain sport got "habbit" what makes them easy picks for the better to bet.
