"Bye Bye Barry" explains why Sanders retired in his prime

• In the doc, Sanders is publicly transparent like never before about his reasons for retiring and acknowledges the disappointment it caused for fans.

Catch up quick: The No. 3 overall pick in the 1989 draft out of Oklahoma State spent 10 seasons with the Lions. He dazzled football fans in Michigan and across the country with his quick twitch jukes, and broke countless records — not that he ever seemed to care about them.

• Sanders' abrupt retirement amid the team's lack of success has haunted the franchise for decades, and was only compounded for fans when Hall of Fame receiver Calvin Johnson did the same thing in 2016.

What they're saying: While the doc featured Johnson and notable guests like Eminem and actor Jeff Daniels, it's been heralded by athletes like LeBron James, who posted this week that he became emotional while watching it.

• "This guy is simply INCREDIBLE!!!!" James wrote.

Between the lines: The film ruffled the feathers of former quarterback Scott Mitchell, who criticized Eminem and others interviewed in the documentary for comments about how they wished Sanders had more help and there was someone else behind center.
