Ive broken out the math before
These guys need to sell about 30 plays a day to net around 100k a year. A lot of them are on multiple sites. A lot of them don't even bet their picks so don't buy into the 10 dime nonsense. They are grinders just like most of the dudes on this site. Thats not a bad thing BTW. I hope when I retire and can do sports full time that I can grind that out
