In an interview with the TODAY Show on Jan. 15, author Jim Murphy reflected on the overnight success of his self-help book 'Inner Excellence,' after Philadelphia Eagles player AJ Brown was seen reading it during a game on Jan.

Eagles wide receiver A.J. Brown ignited a public kerfuffle Sunday when he was spotted reading a book — "Inner Excellence: Train Your Mind for Extraordinary Performance and the Best Possible Life," by Jim Murphy — to inspire himself during the team’s wild-card victory over the Green Bay Packers.

Some in the media have criticized Brown’s reading, believing he was frustrated or disgruntled. On Tuesday, Eagles head coach Nick Sirianni responded to those critics and criticized “lazy” journalism or people who give an opinion on a topic without proper research.
