According to this article, Peyton Manning is disappointed with the coaching changes in Indy. He has not been properly informed about what is going on, and feels out of the loop.

This is awesome. An upset Manning equals a successful division record for our Houston Texans. I hate when people say , "We need to beat them at their best." We need to simply beat the Mannings of Indianapolis, and an upset Peyton with locker room and front office confusion is the best way to do it.
