The book that Philadelphia Eagles star receiver A.J. Brown was reading in a viral video became an overnight best-seller.

One of the Philadelphia Eagles wide receivers, AJ Brown, was seen reading a book on the sidelines during the NFL playoffs. On Sunday (January 12) the Eagles took on the Green Bay Packers with a final score of 22 to 10. Between offensive plays, Fox Sports panned over Brown to find him sitting on the bench, engrossed in a book.

After the game on Sunday, which the Eagles won over the Green Bay Packers, 22-10, Brown expounded on his reading matter, the self-help book “Inner Excellence,” by Jim Murphy. He summed up the book’s message as: “Have a clear mind, and remember that nothing else matters, negative or positive.”
