Philadelphia Eagles head coach Nick Sirianni pushed back on the criticism toward A.J. Brown after the wide receiver was reading a book during a playoff game.

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.
