Scott Soshnick, Eben Novy-Williams and Michael Barr discuss a host of issues related to the business of sports, including NFL star Antonio Brown's threat to retire if he's prevented from wearing his longtime helmet. The NFL's rules prohibit players from wearing non-approved equipment in either practice or games. Brown's helmet hasn't been approved by the National Operating Committee on Standards for Athletic Equipment. Also talked about is Major League Baseball's decision to stage a Yankees-White Sox game in the Iowa cornfield that was the backdrop for the move ``Field of Dreams.'' The game will be played next season. And also discussed is the NFL's new partnership with Sportradar, marking the league's first major step into gambling. The NFL, which is an investor in Sportradar, signed a multiyear deal with data firm, giving it exclusive rights to distribute official data to legal sports-betting operators in the U.S. and abroad.
