NBC NFL rules analyst Terry McAulay and Jeff Pearlman, author of a new book about the zany life and predictable death of the USFL

McAulay, who retired this year after 17 years as an NFL referee, on the concerns he has about the new rules and interpretations of rules in the NFL this season, on his disdain for some of the roughing-the-passer calls in week two, and on his adjustment to TV after a life as an on-field official.

Pearlman on why we should care today about the USFL, which died in the eighties, on the craziest Steve Young story you've ever heard, on what Donald Trump was like as a football team owner, and on the USFL owner who wrote to Trump about wanting to punch him in the face.
