That's basically my philosophy with him as well. I just find it funny how successful he's become with it to move lines considerably. People have been hating on him for years. Props to him for making a good business move with it. Is he the best bettor in the world? I doubt it, but I have no idea. To me, I'm far more impressed by someone who can build a business than someone who can predict fights right.
This same type of hating goes on in the powerlifting/fitness world. Guys like Alan Thrall and Omar Isuf get super popular and make good money their popularity through youtube and social media. They aren't even close to the elite in lifting, which pisses a lot of people off. Who cares - they've marketed a product that the general public buys. That is their goal, which again, is far more impressive and worthwhile to me than moving a lot of weight.
