Eben Novy-Williams and Michael Barr discuss a host of issues related to the business of sports, including NFL quarterback Andrew Luck's shocking decision to retire after just six pro seasons. The 29-year-old is stepping away from the game due to complications from a number of injuries, including a lingering lower leg problem that had cast his 2019 season in doubt. Colts owner Jim Irsay said a healthy Luck could have earned another $500 million in his career. Also discussed is the recent launch of the Atlantic Coast Conference's new cable channel -- the ACC Network -- which is owned by ESPN. The ACC is the fourth major college conference to launch a league-specific network. Also talked about is the U.S. Open, the final Grand Slam on the annual tennis calendar, which starts this week in New York.
