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.

But every head coach has different expectations of their players, particularly on what they should be doing on the sidelines. Yet, don’t expect Eagles coach Nick Sirianni to stop Brown from reading that book. In fact, he’s known about it for a long time now.
