I am not arguing based on logic, or statistics, or anything tangible. It's based on gut.
Also, Peyton Manning does have a history of choking in the playoffs, which we seem to have forgotten. A home loss to a worse Baltimore team fits into that history.
Yeah he did early on though the broncos defense is nothing like the colts, even if the offense is the same. The fact is the divisional round gives the home team the advantage more than any playoff round in America's four major sports. No guarantees, but the bye week does wonders to heal bodies.
