It’s well known that the NFL and the NCAA both frown upon the large amount of office pool sports betting that goes on during their major events: the Super Bowl and the NCAA Men’s Basketball Tournament aka March Madness.
Add to the mix that the high stakes, unregulated dollars are being done mostly in an illegal fashion (that is, sports betting run by individuals may be illegal where you live), you can see why those organizations and local governments may be a bit concerned about the situation.
