In sports, there is always someone winning dominantly. It can get to a point where they are almost always expected to win. By that point do you continue to bet on those favorites to keep winning or does it bore you? Would you enjoy stirring it up a bit just for the fun of it and betting on the underdogs even if the chances are quite low?
I don't care about favourites, I look up to teams that I can assume their possibilities to bring me winning. I either don't maintain a particular strategy for too long when it haven't been enough to brings me winning.
I also can't just
pickeanpick an underdog just because I want to derive fun. Moreover the most excitement fun we can get in sport bets is the winning. So it'll be as stupid if anyone has a winning possibility and decides to intentionally loose it for a fun of mixing strategies or picking teams that your instincts couldn't even convince you to bring you success.
