A look at the plot lines and questions as the 2016 NFL season gets underway:
1. Has John Elway lost the magic touch in Denver?Everything broke the Broncos' way en route to winning Super Bowl 50 in Santa Clara. Elway picked the right free agents, and the decision to go with Gary Kubiak in place of John Fox proved to be the right one. A year later, the Broncos sustained some big losses in free agency (Malik Jackson, Danny Trevethan), saw their prospective No. 1 quarterback (Brock Osweiler) sign with Houston and are faced with the possibility of Mark Sanchez as the Week 1 starter.
