Yes, if he did multiple games per night, I'm quite confident he'd be a far greater than juice loser.Back in the day, many many moons ago, he used to sometimes play like 3 games a night.
The real issue of course is that you need a book to bet, so you pay juice also, or the hold for the book is high.
That's why the key to fading Lang is essentially December to end of January, where he is awful - football is easily his worst sport. Just look at the Two for the Money podcast since its inception to see how bad those guys are. It's like when he was on Dennis Miller's HBO show as a handicapper. It's funny that you can find some of those episodes on youtube still and if you go back historically, he goes like 0-3 or 1-2 nearly every week. He got kicked off the show quickly due to going something like 3-13 on his picks as "Greatest Handicapper". Miller probably laughed his ass off at the end of that.
