ENGLEWOOD, Colo. -- The truest impact of a person is in what he or she leaves behind.
So Peyton Manning's effect on the Broncos cannot yet be measured. Sure, there were two Super Bowl appearances, one world title and 55 wins that the Broncos racked up in the four years in which he was their quarterback.
But Manning's impact on the locker room lingers in his teammates -- not just on the offensive side, but on defense.
You need look no further than the core of the Broncos' defensive alignment and its ensuing mayhem -- linebacker Brandon Marshall for that.
