The Denver Broncos were underdogs at home against the Green Bay Packers last week, so they don't really need much to be motivated these days. They've already locked up a playoff spot, the AFC West is theirs for the taking, and so is the #1 overall seed in the AFC.
The Broncos have plenty to play for beyond just any "disrespect" angle, but everyone knows Sean Payton has a file cabinet -- whether it's all in his head or a literal cabinet of files -- with little things that have been said and done tucked away.
