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.

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.

Philadelphia Eagles coach Nick Sirianni scolded those who may question A.J. Brown's behavior after the All-Pro wide receiver was seen reading a self-help book during the team's playoff victory over the Green Bay Packers on Sunday.
