2. Denver Broncos (Last week: 2)
Peyton Manning is engineering the most prolific offense in the NFL. Color me surprised. Right now, the Broncos are clearly the class of the AFC.
What to know: Remember the concern about Manning’s neck and his deep-ball ability? Well, it’s partially true. Per ESPN Stats & Information, 64 percent of his passes went five yards or fewer, including a 4-of-4 mark to tight end Julius Thomas, who hauled in three touchdowns.
