There is a fantastic feature on Michael Davis and his road to the NFL featured on a Chargers program called Backstage.
It's free on facebook but I couldn't find a way to link it here correctly.
Just search the Chargers Backstage - Offseason Chapter Two and you should find it. His part starts are around the 3:30 point.
There is no mention of BYU as it focuses more on his H.S. years and not really developing until later his Junior year. It did make me think however, how did he end up at BYU? His H.S. coach has a last name of Holmoe is there is relation there?
Either way it's always fun to see guys like Michael be featured and I happy for him.
