Denver running back Phillip Lindsay, one of the season's breakout stars, and Minnesota's Harrison Smith, the best safety in football.

Lindsay on his incredible story--his record-breaking high school career in Denver, his explosive career in college at Colorado, being snubbed from the NFL Scouting Combine, going undrafted, being overly bitter, then having 15 minutes to choose a team (Denver or Baltimore) as an undrafted free agent. And then what it feels like to run for 100 yards against Oakland and Pittsburgh as a rookie who wasn't supposed to make it.

Smith on his road from being someone who never thought he'd play in the NFL to becoming a star in the league, on the science of reading keys and studying opponents, on his interesting relationship with Saints coach Sean Payton, on what makes playing Aaron Rodgers so fun and challenging, and difficult it is to play great defense in the NFL with all the rules favoring offenses.
