They are incredibly good at it. In fact, historically speaking, they hit a number that will be over almost 50% and under almost 50%.
They aren’t fans. They don’t care about biases or what anyone else thinks. If they project a number that is too low or too high, the sharks will eat them alive.
If you think you are smarter than them, go make some money with an under bet. But laughing at fans who are basically in line with all the so called experts, betters, and media/coaches is kind of funny.
But as I said in my other post, there’s a 50% chance their win total will be 9 or less. So there’s a good chance you get to gloat. But if you’re confident, go make some money on that confidence.
