Before Marcus Luttrell made an appearance on ESPN's College GameDay as a guest picker, the former Navy SEAL spent some time talking with the Alabama football team.

The man who inspired the movie 'Lone Survivor' shared his emotionally intense story about a mission in Afghanistan that left all of his team members dead. The story is inspirational on its own, but hearing Luttrell tell it in his own words is chilling.

The video, courtesy of Crimson Tide Productions, shows a six minute excerpt from his visit to Tuscaloosa and it's worth every single second of your time.
