Coming into the 2013 NFL season the expectations are mile high for the Denver Broncos. The window, which was small to start with, is getting smaller for Payton Manning. He will need to lead this team to a title in the next couple of seasons. I will say this Broncos team has all the pieces to the puzzle; they just have to put it together. The 2013 draft and the frenzy of free agency are in the books, so here are my top five teams coming into the season.
