Barry Sanders knows more than anyone how Andrew Luck is feeling after the quarterback announced his abrupt retirement from the NFL after seven short seasons with the Indianapolis Colts.

Sanders spent 10 seasons with the Detroit Lions before his own abrupt retirement in 1999. The Hall of Fame running back, in an interview Saturday with the New York Daily News, commended Luck over the way he handled his retirement.

“It's a personal decision,” Sanders told the newspaper. “It's extremely difficult [for Luck]. You could tell, just listening to his press conference. He's a bright, sharp, young man. He's got many great options, I would assume, but it's tough for everyone involved. I think he handled it about as well as you could.”

The Daily News noted that Sanders simply faxed the Wichita Eagles in July 1999 that his decision to retire stemmed from his lack of desire to keep playing football. He then revealed in a book the organization’s decision to trade or let go key players helped influence his retirement decision.
