This weekend, football fans will be glued to the TV screen for the start of playoff season in the NFL. While the recipe for success for most championship caliber teams is to be led by an elite level quarterback, it never hurts to have a solid back-up.

Adam Lazarus, author of the new book "Best of Rivals: Joe Montana, Steve Young, and the Inside Story behind the NFL's Greatest Quarterback Controversy," joins the show.
