Will Marvin Mims Jr. break out for the Broncos this season?

Part of what makes an NFL season so captivating -- much like a good book -- is the out-of-nowhere plot twists.

Who would have guessed, for example, that the biggest storyline to emerge from January's NFC wild-card game between the Philadelphia Eagles and Green Bay Packers would be a player's reading habits.

That player, of course, was star receiver A.J. Brown. When cameras panned the Eagles' sideline during the second half, the image of Brown reading Jim Murphy's "Inner Excellence" on the bench was broadcast to a national audience.

Given Brown's quiet game (one catch for 10 yards on three targets), the wide assumption was that it was a sign of frustration. But it turns out Brown was using the book to tune in, not out.

"I'm just using it for football, to have my peak performance, trying to have my best self out there on the field," he told ESPN at the time.

Sales for "Inner Excellence" surged across the country and Brown leaned into the newly revealed part of his persona. He published his own reading list on social media earlier this offseason, encouraging his followers to find a book that interests them "so you can become a better version of yourself."
