Fantasy did but not this fantasy. This has just made it a outright gusher. Homemade fantasy hugely boosted the NFL but not as much as the internet and online gambling.
They aren't paying millions to NCAA to play games on a Thurs in front of a half empty stadium for fantasy. The real money and eyes are still with illegal online gambling. There will still be plenty of money to be made with illegal fantasy gambling. This stuff is here to stay.
