King is a true deep threat, and should immediately be a dangerous weapon in Denver.
He isn't a physical receiver and would definitively benefit by adding some weight, but King will be able to stretch the field and should come up with some big plays for the Broncos early in his career.
He's at his best when lined up on the outside, and should rotate in behind Demaryius Thomas and Eric Decker.
Manning will feed the ball to Thomas, Decker and Wes Welker, but King could establish himself as the fourth option in the Broncos offense.
He won't be a viable fantasy option early on, but should anyone go down with an injury he could become a surprising sleeper to keep an eye on.
Thomas, Welker and Decker are firmly entrenched as the Broncos' top receivers, but Denver doesn't have a ton of depth at the position.
King will compete with Greg Orton and Gerell Robinson for the job as the fourth receiver.
A job definitely won't be guaranteed to King, but his speed makes him an interesting option especially since neither Welker nor Decker is a consistent downfield threat.
Nothing is guaranteed in the fifth round, but King does one thing well and that's really all you can hope to find this late in the draft.
There were other receivers on the board with more upside, but the Broncos are building for the immediate future. King can immediately step on the field and be a guy that defenses need to be aware of at all times.
