IMO, Desmond King is a classic case of a football player falling. Look at Aaron Rodgers back several years ago. Rodgers was expected to go in the top few picks. Instead he sat and sat through over half the first round until the Packers finally picked him up at Pick #24. I would also add that these NFL Experts let Tom Brady slide all the way to the 6th Round.
The Draft is an inexact science. Perception becomes reality. Great players slide. Players that will be a bust get hyped into high selections. Anyone remember Troy Williamson, the Vikings picked him at #7 and he was a complete bust.
The Hype was all going King's way after his junior season. After his senior season, King played in the Senior Bowl and the criticisms started mounting so his draft stock fell. Desmond King ran a 4.5 second 40 at Iowa's Pro Day. That is not all that slow.
Here is a good story about Aaron Rodgers fall. Rodgers was predicted by many to be the Top Pick in the Draft.
