They might as well start a Gambler's Bowling Tour where backers, the crowd, the fans, and the bowler's can bet it up.
I would venture to say that the current PBA tour is interested in being clean cut and maybe something your family would want to watch and respect, but let's be real, bowling is about swilling beer, eating onion rings, and losing all the money in your wallet in the brackets lol, so they might as well bite the bullet and make the tour reflect these realities.
But really though, I have never seen darts on television and the dart player on the ESPN list made multiples of the highest season tour earnings ever!
