Philadelphia Eagles receiver AJ Brown got in a little reading during the birds' 22-10 victory over the Green Bay Packers on Sunday during a Wild Card round matchup.

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.
