Drafting as a science is inexact.
All teams have their "hits" and "misses."
Professional scouts watch the players in actual games, pour over hi-tech film with advantageous angles thru hi-tech machinery, speak to the player, speak to their coaches----and yet no scout and no team has drafting down to an exact science.
In 2011, I pounded the table, early on, for Cameron Jordan over Adrian Clayborn, but the next year, I was equally convinced that Morris Claiborne would develop into an all pro CB---hits and misses
Last year on this board there were many who felt that Bosa would not translate well to the NFL and thus certainly would not be a top 5 pick.
So for all of us who have "favorite" players only to have the board react in a negative manor----take heart---no one really knows. Certainty only exists 1 or 2 or 3 years down the road, in hindsight.
