You're really good at this stuff man, my fringe sport is NBA all day long... football betting is evil, but that's the sport we love the most anyways, and can't live without.
NBA can't be your fringe sport. Whole point is to pick sport where you have advantage over bookie. We are talking eSports, table tennis, sepaktakrow...
You know something where algorithms aren't that polished.
NBA can be a sport where you know most but you will not find value odds there.
