It does not.
His overriding point is the teams and scouts don't build a ranking of players from 1 to 25, or 1 to 50. But they absolutely slot players into rounds. Crap, we've seen the in the past that the Cowboys draft board has been leaked and they have guys bunched up by the round they think they will go.......... ergo, they put a value on a player. In other words, they wouldn't draft Pollard in the 2nd round even though they liked him, but they would entertain him in the 4th because that's where they saw his ranking/value.
The Cowboys wanted Pollard but they wouldn't use their 2nd or 3rd on him because they believed they could get two better players at those spots and then get the value in Pollard in the 4th.
Value can translate onto the field. Because if you take a guy with a 6th round value in the 2nd round and pass up a real 2nd round player, you might be costing yourself TWO good players. Hence the concept of value and how it translates to the roster. Put it another way. If we take Dak Prescott in the 2nd round, we cost ourselves Jaylon Smith and it's unlikely that the guy we would have taken in Dak's spot in the 4th would turn out jsut as good as Smith. Are we a better team with Prescott and some schlub in the 4th round or better with Smith AND Prescott?
